[jira] [Comment Edited] (OAK-5762) [Oak Lucene] Several full-text operators do not work (NOT, !, AND)

---------------------------------------------------------------

I think the documentation needs to be updated. Links:
* Contains: http://jackrabbit.apache.org/oak/docs/query/grammar-xpath.html#condition
* Fulltext: http://jackrabbit.apache.org/oak/docs/query/query-engine.html#Full-Text_Queries
* Lucene Syntax: https://lucene.apache.org/core/4_7_1/queryparser/org/apache/lucene/queryparser/classic/package-summary.html

For the cases above:
* AND is the default operator, so instead of {{'response AND layout'}} this works: {{'response layout'}}. This also works: {{'response \+layout'}}; both converted to {{\+(\+:fulltext:response \+:fulltext:layout)}}
* NOT is currently supported only using {{\-}} (as you noted), so instead of {{'response NOT layout'}} use {{'response \-layout'}}, converted to {{\-:fulltext:layout \+:fulltext:response}}
* {{'response !layout'}}: not sure what the intended behavior is... maybe NOT? This is not supported by Apache Lucene.
* {{'response OR layout'}}: this is working, converted to {{\+(:fulltext:response :fulltext:layout)}}

For the cases above:
* AND is the default operator, so instead of 'response AND layout' this works: 'response layout'. This also works: 'response +layout'; both converted to +(+:fulltext:response +:fulltext:layout)
* NOT is currently supported only using - (as you noted), so instead of 'response NOT layout' use 'response -layout', converted to -:fulltext:layout +:fulltext:response
* 'response !layout': not sure what the intended behavior is... maybe NOT? This is not supported by Apache Lucene.
* 'response OR layout': this is working, converted to +(:fulltext:response :fulltext:layout)
