Full-text search
Use SQL commands for full-text search. The SQL plugin supports a subset of the full-text queries available in OpenSearch.
To learn about full-text queries in OpenSearch, see Full-text queries.
Match
To search for text in a single field, use MATCHQUERY
or MATCH_QUERY
functions.
Pass in your search query and the field name that you want to search against.
SELECT account_number, address
FROM accounts
WHERE MATCH_QUERY(address, 'Holmes')
Alternate syntax:
SELECT account_number, address
FROM accounts
WHERE address = MATCH_QUERY('Holmes')
account_number | address |
---|---|
1 | 880 Holmes Lane |
Multi match
To search for text in multiple fields, use MULTI_MATCH
, MULTIMATCH
, or MULTIMATCHQUERY
functions.
For example, search for Dale
in either the firstname
or lastname
fields:
SELECT firstname, lastname
FROM accounts
WHERE MULTI_MATCH('query'='Dale', 'fields'='*name')
firstname | lastname |
---|---|
Dale | Adams |
Query string
To split text based on operators, use the QUERY
function.
SELECT account_number, address
FROM accounts
WHERE QUERY('address:Lane OR address:Street')
account_number | address |
---|---|
1 | 880 Holmes Lane |
6 | 671 Bristol Street |
13 | 789 Madison Street |
The QUERY
function supports logical connectives, wildcard, regex, and proximity search.
Match phrase
To search for exact phrases, use MATCHPHRASE
, MATCH_PHRASE
, or MATCHPHRASEQUERY
functions.
SELECT account_number, address
FROM accounts
WHERE MATCH_PHRASE(address, '880 Holmes Lane')
account_number | address |
---|---|
1 | 880 Holmes Lane |
Score query
To return a relevance score along with every matching document, use SCORE
, SCOREQUERY
, or SCORE_QUERY
functions.
You need to pass in two arguments. The first is the MATCH_QUERY
expression. The second is an optional floating point number to boost the score (default value is 1.0).
SELECT account_number, address, _score
FROM accounts
WHERE SCORE(MATCH_QUERY(address, 'Lane'), 0.5) OR
SCORE(MATCH_QUERY(address, 'Street'), 100)
ORDER BY _score
account_number | address | score |
---|---|---|
1 | 880 Holmes Lane | 0.5 |
6 | 671 Bristol Street | 100 |
13 | 789 Madison Street | 100 |
