In the Label field, enter a unique identifier for this stage or leave blank to use the default value.

In the Condition field, enter a script that results in true or false, which determines if the stage should process, or leave blank.

In the Tagger Collection field, enter where the tagger request is sent. The default is the query_rewrite collection for the application selected. You must enter a collection with only one shard because Text Tagger does not support multi-shard collections. Template expressions are supported.

In the Param to Tag field, enter a value of q, which is the name of the parameter in the request containing text to tag. This field is ignored on DSL requests.

In the Save Tags in Context field, enter the tags to save in context instead of applying directly to the incoming query in this stage. This enables downstream stages to apply the tags after completing other processing. This field is ignored on DSL requests.

Select the following checkboxes:

In the Filter Override field, enter your filter to override filtering for built-in tagger doc types.

In the Original Term Boost for Synonyms field, enter the boost to use for the original term during synonym expansion. For example, 2. To disable this function, enter -1.

In the Default Phrase Boost field, enter the boost to use as a default for phrases that do not have a boost value set. For example, 2. To disable this function, enter -1.

In the Default Phrase Slop field, enter the distance between the terms of the query while still considering it a phrase match. For example, 10.

In the Overlapping Tag Policy field, select the default value of longest_dominant_right to ensure the retained tags have no overlaps. The value is the algorithm that determines which tags in an overlapping set should be retained, versus being pruned away. On DSL requests, this field is ignored so the default value of longest_dominant_right is always used. The available options correspond to Solr Tagger Handler overlaps: all, no_sub, or longest_dominant_right. Setting the value to all or no_sub allows more rewrites to potentially be applied to a query, but can increase the chance of producing undesirable rewrites.

In the Additional Params to be included in the Text Tagger Request section, enter optional values you want to include.

In the Max Wait for Lookup (ms) field, enter the number of milliseconds to wait for the call to the remote tagger collection to return. For example, 500. To disable this function, enter -1.

In the Skip Query Regex field, enter the pattern that identifies queries that are skipped because they contain that pattern. For example, you may want to skip single term queries with wildcards.

In the Rollup weight field, enter the field name to use for signal weights. For example, weight_d.

In the Rollup weight strategy field, select one of the following methods to use when rolling up the weight:

In the Final Boost Weight Expression field, enter the optional expression to compute the final boost weight using a combination of fields returned by Solr. For example, score and weight_d. Set to weight_d for similar behavior as older versions. Another example is math:log(weight_d + 1) + 10 * math:log(score+1).

In the Document Weights Context Key field, enter the context key in which to save boosts for docId:weight_d.

In the Query Param field, enter the default value of q, which is the name of the parameter in the request containing query to boost.

In the Label field, enter a unique identifier for this stage or leave blank to use the default value.

In the Condition field, enter a script that results in true or false, which determines if the stage should process, or leave blank.

In the Number of Results field, enter the number of query fields to return. For example, 10.

In the Result Offset field, enter the value that designates the starting position of the first result from the beginning of the data being queried. Offset is zero-based, so a value of 9 counts from 0 through 9 and the first record returned is the 10th record discovered in the query.

In the Results Sort Order section, enter values for the following fields:

In the Search Fields section, enter the field name and boost values to include in this stage.

In the Return Fields section, enter the field names to include in this stage.

In the Number of Lexical Results field, enter the number of lexical search results to include in re-ranking. For example, 1000. A value is 0 is ignored.

In the Vector Query Field, enter the name of the Solr field for k-nearest neighbor (KNN) vector search.

In the Vector Input field, enter the location from which the vector is retrieved. Template expressions are supported. For example, a value of <ctx.vector> evaluates the context variable resulting from a previous stage, such as the LWAI Vectorize Query stage.

In the Vector Query Weight field, enter the relative weight of the vector query. For example, 0.7.

Select the Use KNN Query checkbox to use the knn query parser and configure its options. This option cannot be selected if Use VecSim Query checkbox is selected. In addition, Use KNN Query is used if neither Use KNN Query or Use VecSim Query is selected.

In the HTTP Method field, select POST.

Select the Allow Federated Search checkbox to enable the use of Solr collection and shards parameters for this stage.

Select the Generate Response Signal checkbox to generate a response signal containing metadata about the response from Solr. Response signals are used by App Insights and experiments. This setting only applies if the searchLogs and signals features are enabled for the collection. To avoid generating response signals as Users type, do not select this option.

In the Exclude Response Signal Criteria section, enter query parameters and Regex patterns to prevent generating a response signal based on specific parameters in the query. For example, use these fields to enable response signals in general, but to disable for auto-complete queries.
