Solr Query Syntax
The standard Solr Query Parser syntax is a superset of the ![[WWW]](/wiki/modern/img/moin-www.png){kind=small}
Lucene Query Parser syntax.
Differences From Lucene Query Parser
Differences in the Solr Query Parser include
Range queries [a TO z] and prefix queries a* are constant-scoring (all matching documents get an equal score). The scoring factors tf, idf, index boost, and coord are not used. There is no limitation on the number of terms that match (as there was in past versions of Lucene).
Lucene 2.1 has also switched to use ConstantScoreRangeQuery for its range queries.
A * may be used for either or both endpoints to specify an open-ended range query.
field:[* TO 100] finds all field values less than or equal to 100
field:[100 TO *] finds all field values greater than or equal to 100
field:[* TO *] matches all documents with the field
Pure negative queries (all clauses prohibited) are allowed.
-inStock:false finds all field values where inStock is not false
-field:[* TO *] finds all documents without a value for field
A hook into FunctionQuery syntax. Quotes will be necessary to encapsulate the function when it includes parentheses.
Example: _val_:myfield
Example: _val_:"recip(rord(myfield),1,2,3)"
Although not technically a Syntax difference, please note that if you use the Solr " DateField" type, any queries on those fields (typically range queries) should use either the Complete ISO 8601 Date syntax that field supports, or the DateMath Syntax to get relative dates. Examples:
timestamp:[* TO NOW]
createdate:[1976-03-06T23:59:59.999Z TO *]
createdate:[1995-12-31T23:59:59.999Z TO 2007-03-06T00:00:00Z]
pubdate:[NOW-1YEAR/DAY TO NOW/DAY+1DAY]
createdate:[1976-03-06T23:59:59.999Z TO 1976-03-06T23:59:59.999Z+1YEAR]
createdate:[1976-03-06T23:59:59.999Z/YEAR TO 1976-03-06T23:59:59.999Z]
URL Escaping Special Characters
Please note that many characters in the Solr Query Syntax (most notable the plus sign: "+") are special characters in URLs, so when constructing request URLs manually, you must properly URL-Encode these characters.
