> Parse Interval Query from JSON API
> ----------------------------------
>
> Key: SOLR-13764
> URL: https://issues.apache.org/jira/browse/SOLR-13764
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: query parsers
> Reporter: Mikhail Khludnev
> Priority: Major
>
> h2. Context
> Lucene has Intervals query LUCENE-8196. Note: these are a kind of healthy
> man's Spans/Phrases. Note: It's not about ranges nor facets.
> h2. Problem
> There's no way to search by IntervalQuery via JSON Query DSL.
> h2. Suggestion
> * Create classic QParser \{{ {!interval df=text_content}a_json_param}}, ie
> one can combine a few such refs in {{json.query.bool}}
> * It accepts just a name of JSON params, nothing like this happens yet.
> * This param carries plain json which is accessible via {{req.getJSON()}}
> {\{{}}
> {{ query: {bool:{should:[}}
> {{ \{interval:i_1},}}
> {{ {interval:
> {query:i_2, df:title}
> }}
> {{ }]}},}}
> {{ params:{}}
> {{ df: description_t,}}
> {{ i_1:\{phrase:"lorem ipsum"},}}
> {{ i_2:{ unordered: [
> {term:"bar"}
> ,\{phrase:"bag ban"}]}}}
> \{{ }}}
> {{}}}
> h2. Challenges
> * I have no idea about particular JSON DSL for these queries, Lucene API
> seems like easy JSON-able. Proposals are welcome.
> * Another awkward things is combining analysis and low level query API. eg
> what if one request term for one word and analysis yield two tokens, and vice
> versa requesting phrase might end up with single token stream.
> * Putting json into Jira ticket description
> h2. Q: Why don't..
> .. put intervals DSL right into {{json.query}}, avoiding these odd param
> refs?
> A: It requires heavy lifting for {{JsonQueryConverter}} which is streamlined
> for handling old good http parametrized queires.
