[doc] Reorganize and clean Java documentation This commit reorganizes the docs to make Java API docs looking more like the REST docs. Also, with 2.0.0, FilterBuilders don't exist anymore but only QueryBuilders. Also, all docs api move now to docs/java-api/docs dir as for REST doc. Remove removed queries/filters ----- * Remove Constant Score Query with filter * Remove Fuzzy Like This (Field) Query (flt and flt_field) * Remove FilterBuilders Move filters to queries ----- * Move And Filter to And Query * Move Bool Filter to Bool Query * Move Exists Filter to Exists Query * Move Geo Bounding Box Filter to Geo Bounding Box Query * Move Geo Distance Filter to Geo Distance Query * Move Geo Distance Range Filter to Geo Distance Range Query * Move Geo Polygon Filter to Geo Polygon Query * Move Geo Shape Filter to Geo Shape Query * Move Has Child Filter by Has Child Query * Move Has Parent Filter by Has Parent Query * Move Ids Filter by Ids Query * Move Limit Filter to Limit Query * Move MatchAll Filter to MatchAll Query * Move Missing Filter to Missing Query * Move Nested Filter to Nested Query * Move Not Filter to Not Query * Move Or Filter to Or Query * Move Range Filter to Range Query * Move Ids Filter to Ids Query * Move Term Filter to Term Query * Move Terms Filter to Terms Query * Move Type Filter to Type Query Add missing queries ----- * Add Common Terms Query * Add Filtered Query * Add Function Score Query * Add Geohash Cell Query * Add Regexp Query * Add Script Query * Add Simple Query String Query * Add Span Containing Query * Add Span Multi Term Query * Add Span Within Query Reorganize the documentation ----- * Organize by full text queries * Organize by term level queries * Organize by compound queries * Organize by joining queries * Organize by geo queries * Organize by specialized queries * Organize by span queries * Move Boosting Query * Move DisMax Query * Move Fuzzy Query * Move Indices Query * Move Match Query * Move Mlt Query * Move Multi Match Query * Move Prefix Query * Move Query String Query * Move Span First Query * Move Span Near Query * Move Span Not Query * Move Span Or Query * Move Span Term Query * Move Template Query * Move Wildcard Query Add some missing pages ---- * Add multi get API * Add indexed-scripts link Also closes #7826 Related to https://github.com/elastic/elasticsearch/pull/11477#issuecomment-114745934 2015-06-24 23:27:19 +02:00			`[[java-query-dsl-exists-query]]`

Build that java api docs from a test (#24354) We've had `QueryDSLDocumentationTests` for a while but it had a very hopeful comment at the top about how we want to make sure that the example in the query-dsl docs match up with the test but we never had anything that made sure that they did. This changes that! Now the examples from the query-dsl docs are all built from the `QueryDSLDocumentationTests`. All except for the percolator example because that is hard to do as it stands now. To make this easier this change moves `QueryDSLDocumentationTests` from core and into the high level rest client. This is useful for two reasons: 1. We expect the high level rest client to be able to use the builders. 2. The code that builds that docs doesn't check out all of Elasticsearch. It only checks out certain directories. Since we're already including snippets from that directory we don't have to make any changes to that process.
