Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiM2ZhODky... ) / Improvement ( https://hibernate.atlassian.net/browse/HSEARCH-3327?atlOrigin=eyJpIjoiM2Z... ) HSEARCH-3327 ( https://hibernate.atlassian.net/browse/HSEARCH-3327?atlOrigin=eyJpIjoiM2Z... ) Add options for match predicates targeting multiple fields ( https://hibernate.atlassian.net/browse/HSEARCH-3327?atlOrigin=eyJpIjoiM2Z... ) Change By: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *Note*: This is slightly different from [ HSEARCH-917 ] and [https://hibernate.atlassian.net/browse/ HSEARCH-2589 |https://hibernate.atlassian.net/browse/HSEARCH-2589|smart-link] , though related. This ticket is about the behavior when a single predicate target multiple fields, while the others are about the behavior when a single predicate has multiple search terms. We should offer additional parameters to match predicates allowing to select exactly how we want the predicate to behave when multiple fields are targeted: * how documents are matched: at least one match is required per field, or at least one on any field, ... * how score is computed. We will probably have to move the handling of multiple fields to the backend layer, i.e. not create a boolean junction in the engine and ask the backend to create one predicate for each field, but instead just ask the backend to create a single predicate for *all* the fields. See for example the “multi-match” query in Elasticsearch: [ https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl... |https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html] And in particular the "type" parameter: [ https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl... |https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html#multi-match-types] ( https://hibernate.atlassian.net/browse/HSEARCH-3327#add-comment?atlOrigin... ) Add Comment ( https://hibernate.atlassian.net/browse/HSEARCH-3327#add-comment?atlOrigin... ) Get Jira notifications on your phone!
