This project is a plugin for vespa.ai search engine that includes a new Searcher capable of creating a map of matches for your analyzed string, which can show the locations of a query in the text.
mvn install package -f vespa-searcher-match-map/On your search definition file, please include snip as a query command in your fields that are going to be mapped. snip is incompatible with Vespa's dyn summarization (summary: dynamic) and requires a highlight configuration (bolding: on).
In orther to retrieve a dyn summarization, please include dynsnip as a query command too.
field field_name type string {
indexing: summary | index
bolding: on
query-command: snip
query-command: dynsnip
}
On your services.xml file, add the searcher (com.potelo.prelude.searcher.SnipperSearcher) into a search chain:
<?xml version="1.0" encoding="utf-8" ?>
<services version="1.0">
<admin version="2.0">
<adminserver hostalias="node1" />
</admin>
<container version="1.0">
<search>
<chain id="default" inherits="vespa">
<searcher id="com.potelo.prelude.searcher.SnipperSearcher" />
</chain>
</search>
<nodes>
<node hostalias="node1" />
</nodes>
</container>
</services>{
