Results and page concepts

Experience Optimizer

This topic provides information about page components you can manage to improve query results in Experience Optimizer.

Document grouping

Experience Optimizer lets you define categories and group documents that are relevant to each other.

Options to group documents include:

• Block or boost. For example, promote a new document group to the top of the results for greater visibility.
• Apply rules individually to documents within a group. For example, boost ballet-related documents to the top of the group if a specific user searches for ballet dance contest.

Best practices

These parameters group documents, and are defined in the Additional Query Parameters Stage:

Parameter Name	Parameter Value	Update Policy
group	true	default
group.format	grouped	default
group.ngroups	true	default
group.field	style_id_s	default

For more information about adding a query pipeline and additional query parameters, see:

• Add a Query Pipeline Stage
• Additional Query Parameters Stage

Add a Query Pipeline Stage

In the Query Workbench, click Add a Stage to add query pipeline stages that can perform query setup, results relevancy, troubleshooting, and more.

The Solr Query stage is the only pipeline stage that is required for querying processes to complete, and therefore exists in every query pipeline. It is always the last stage in a series.

See these pages for more information:

• Query Workbench
• Query Pipeline Stages
• Solr Query stage

Collapse/Expand parser grouping

The Collapse/Expand parser allows grouping with the following parameters:

Parameter Name	Parameter Value
expand	true
enableElevation	true
group	false

See Collapse and Expand Results for more information.

Search rewrites

Search rewriting lets you modify search queries to more accurately reflect the intentions of your customers.

These functions let you:

• Create search rewrites manually.
• Edit, test, review and publish the search rewrites generated automatically from signals data.

For example, create a misspelling search rewrite to correct common spelling mistakes entered for a particular document. The misspelled query will then produce the same results as a correctly spelled search.

Experience Optimizer provides four rewrite types:

• Use Experience Optimizer query rewrites - improves poorly performing searches.
• Use Experience Optimizer query rewrites - corrects common spelling mistakes.
• Use Experience Optimizer query rewrites - identifies documents with matching phrases.
• Use Experience Optimizer query rewrites - includes alternative words with the same meaning.

Use Experience Optimizer query rewrites

You can create query rewrite rules in Experience Optimizer. This is similar to using the Rules Editor to create query rewrite rules, except there are additional options in Experience Optimizer.

1. In Managed Fusion, navigate to Relevance > Rules > Optimizer.
2. Enter a search term or phrase in the search bar.
3. Click Start Task.
4. Hover your cursor next to the query. A + button will appear:
5. Click the + button. A list of query rewrites options will appear: Head/Tail, Misspelling, Phrase, Synonym, and Remove Words.
6. Click on the type of rule you’d like to configure.

Head/Tail

You can create a Head/Tail rewrite to improve search results using methods other than correcting for misspellings or synonym expansion. When a poorly defined search term is identified, the original term is replaced by an improved search term.

For example, a search for benefits enrollment could be improved by using the search term benefits enrollment+year:"2021" (in this case making use of the year field in the data).

Most Head/Tail rewrites are typically created automatically via machine learning. However, if desired, custom rewrites can be manually created using the following steps.

1. From the list of query rewrite options, select Head/Tail. A form will appear:

   

   This form contains the following fields:

   Parameter	Description	Example Value
   Tail Query	The tail query itself.	benefits enrollment
   Improved Query	The query that will replace the tail query phrase.	benefits enrollment+year:"2021"
   Tags	Optional metadata tags that can be used to identify and organize rewrites.	enrollmentpacket

2. Enter one or more improved search terms in the Improved Query field.

3. Click the Save button.

The search is re-run using the improved search term, and a Search box information panel drops down to show that the new query rewrite has fired:

Misspelling

You can create a misspelling query rewrite to detect and correct common spelling mistakes. When a customer enters a search term containing a known misspelling, the incorrect spelling is replaced with the spelling correction.

For example, if your clients frequently misspell or mistype the word questionnaire as questionare, you can set up a query rewrite to automatically correct it.

1. From the list of query rewrite options, select Misspelling. A form will appear:

   

   This form contains the following fields:

   Parameter	Description	Example Value
   Misspelled Term	The phrase itself.	questionare
   Corrected Term	The term that will replace the misspelled term.	questionnaire
   Action	Action to perform.	expand
   Confidence	Confidence score from the phrase job. A confidence level of 1 represents 100% confidence. For rules created automatically via machine learning, the confidence level reflects the output from the machine learning model.	1
   Tags	Optional metadata tags that can be used to identify and organize rewrites.	enrollmentpacket

2. Enter one or more spelling corrections in the Corrected Term field.

3. Click the Save button.

The search is re-run using the corrected spelling, and a Search box information panel drops down to show that the new query rewrite has fired:

Phrase

You can use query rewriting to identify phrases used in search terms so that products with matching phrases are boosted in the search results. This is helpful when users do not use quotation marks to identify phrases in their search terms.

For example, without phrase detection a search for the words background check would show results for both background and check. With phrase detection, this search would correctly boost results for "background check".

1. From the list of query rewrite options, select Phrase. A form will appear:

   

   This form contains the following fields:

   Parameter	Description	Example Value
   Surface Form	The phrase itself.	background check
   Word Count	Indicates how many words are included in the phrase.	2
   Confidence	Confidence score from the phrase job. A confidence level of 1 represents 100% confidence. For rules created automatically via machine learning, the confidence level will reflect the output from the machine learning model.	1
   Tags	Optional metadata tags that can be used to identify and organize rewrites.	enrollmentpacket
   Phrase Count	Denotes how many times this phrase was found in the source. This value is automatically set via machine learning. It does not need to be set manually.	5
   Boost Factor	The factor to use to boost this phrase in matching queries.	2.0
   Slop Factor	Phrase slop, or the distance between the terms of the query while still considering it a phrase match.	10

2. Enter the number of words in the phrase in the Word Count field.

3. Click the Save button.

The search is re-run, with your search words identified as a phrase, and a Search box information panel drops down to show that the new query rewrite has fired:

Synonym

You can specify synonyms for a specified search term so that alternative words with the same meaning are automatically used in the search query. When a customer enters a search term with a synonym match, the alternative words are used instead of, or in addition to, the original search term.

For example, the search term questionnaire could have the synonyms application and survey.

1. From the list of query rewrite options, select Synonym. A form will appear:

   

   This form contains the following fields:

   Parameter	Description	Example Value
   Surface Form	The term that has synonyms.	questionnaire
   Direction	With a oneway search, the original search term is replaced by the synonym. In the preceding example, questionnaire would be replaced by the alternative words application and survey. With a symmetric search, the search query is expanded to include the original term and the synonyms, resulting in a greater number of potential hits. In the preceding example, this time the query would include questionnaire, application, and survey.	symmetric
   Synonym Mappings	Synonyms for the surface form.	application, survey`
   Confidence	Confidence score from the phrase job. A confidence level of 1 represents 100% confidence. For rules created automatically via machine learning, the confidence level will reflect the output from the machine learning model.	1
   Tags	Optional metadata tags that can be used to identify and organize rewrites.	enrollmentpacket
   Count	How many times this term occurred in the signal data when it was discovered. This value is optional when a rewrite is being defined manually.	5

2. Choose whether the direction is oneway or symmetric.

3. Enter one or more alternative words in the Synonym Mappings field.

4. Click the Save button.

The search is re-run using the synonyms, and a Search box information panel drops down to show that the new query rewrite has fired:

Remove Words

The Remove Words feature is available in Fusion 5.4 and later.

You can create a Remove Words query rewrite to remove words from a query. This query rewrite is helpful when a word in the search query does not add value to the search results.

For example, you can rewrite a search query for case study examples to remove examples and then display results for case study.

1. From the list of query rewrite options, select Remove Words. A form appears:

   

2. This form contains the following fields:

Parameter	Description	Example Value
Phrase to remove	The words to remove from the trigger phrase.	examples
Trigger phrases	The query that prompts the removal of the phrase. The trigger phrase is not necessarily a complete query. If the query contains the trigger phrase, then Fusion removes the phrase in the Phrase to Remove field.	case study examples

1. Enter a phrase to remove and a trigger phrase. Note that the phrase to remove is auto-populated with the query.
2. Click Save.

The search is re-run, and a Search box information panel drops down to show that the new query rewrite has fired:

Sometimes, rules created in the Rules Editor and Experience Optimizer conflict with each other. For example, if you have three rules to boost, bury, and block a document, Experience Optimizer highlights these conflicting rules so you can address them.

To highlight conflicting rules, the Rules Fired section displays a red warning icon next to the dominant rule and a red flag on the conflicting rules.

Click the Edit button to view the details of the conflicting rules and resolve the conflict.

The details of the conflicting rules affecting specific documents are found in the Document Details panel. Click the Start Task button, and then click the Document Details button.
