that's not gonna work ... text:query:match_phrase
is an invalid SPARQL predicate. You can try to put the "match_phrase" into the query string, but I don't think it will work. A "query string query" is used via the ES Java API [1] Syntax can be found online [2] [1] https://github.com/apache/jena/blob/master/jena-text-es/src/main/java/org/apache/jena/query/text/es/TextIndexES.java#L409 [2] https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html On 13.01.21 06:58, Deepali Singhavi wrote: > Hi Andy, > > I have gone through the elastic search documentation and I know there is an > option of *match_phrase *but I want to know how it will work with SPARQL > query. > > For example I have tried the below query but it is not working so I want to > understand the syntax. > > prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> > prefix star: <http://stardog.com/tutorial/> > PREFIX text: <http://jena.apache.org/text#> > select ?subject ?object > from <urn:music> > WHERE { > ?subject *text:query:match_phrase* (star:description "\"rock band Queen\"") > . > ?subject star:description ?object . > } > > Regards, > Deepali > > On Tue, Jan 12, 2021 at 7:52 PM Andy Seaborne <a...@apache.org> wrote: > >> Check the documentation for Lucene and ElasticSearch. jena-text passes >> the text query straight through. >> >> On 12/01/2021 13:32, Deepali Singhavi wrote: >>> Hi, >>> >>> I am trying to match exact phrases using SPARQL but for Lucene it is >>> working but not for Elastic search.
