Full-text queries #

Queries that analyze text: the match family, query_string, boolean composition, the span family and the intervals rule language for positional logic. Scoring queries that never touch an analyzer — similarity, scripts, proximity — are the specialized queries.

The match family #

• Match — analyzed text, number, date or boolean
• Phrase — the exact term sequence, in order (also accepted: match_phrase)
• Match all — every document (and match_none)
• Multi-match — one text across several fields, per-field boosts

Composition and compact syntax #

• Boolean query — must / filter / should / must_not
• Query string — the compact field:value AND … syntax (also powers ?q=)

Positional logic #

• Span queries — span_term / span_near and friends, term positions exposed
• Intervals — the rule language for proximity: sequences, gaps, unions, filters

SQL twins: match → MATCH(field, '…'), phrase → MATCH_PHRASE(field, '…'), match_all → a bare SELECT, and bool composes with AND / OR / NOT. The rest — query_string, multi_match, the span family, intervals, and the specialized queries — stay DSL-side for now.
