Text Tagger Stage

This stage uses the SolrTextTagger handler to identify known entities in the query by searching the _query_rewrite collection (or the _query_rewrite_staging collection in the case of the Fusion AI query rewriting Simulator) to find matching spelling corrections, phrase boosts, underperforming query improvements, and synonym expansions in order to perform query rewriting.

When the query rewrite entails boosting, the boosting is applied later in the pipeline, during the Solr Query stage.

Note
Although this stage is available without a Fusion AI license, it is only effective after running Fusion AI jobs or creating Fusion AI rules. See Query Rewriting for details.

Configuration

Tip
When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.
