Hannes Ljungberg 0b51a4f894 Fixed #28194 -- Added support for normalization and cover density to SearchRank. 2020-03-23 11:00:55 +01:00
Baptiste Mispelon 3baf92cf82 Fixed #31340 -- Allowed query expressions in SearchQuery.value and __search lookup. 2020-03-16 10:27:23 +01:00
Mariusz Felisiak e2417010da Refs #31304 -- Added tests for using __search lookup with combined SearchQuerys with the same config. 2020-03-13 12:06:28 +01:00
Baptiste Mispelon dd704c6705 Refs #31340 -- Simplified SearchQuery by making it subclass Func. 2020-03-13 11:38:43 +01:00
Simon Charette 7c8b043a03 Refs #31304 -- Made __search lookup default to its rhs' config. 
This make the SearchLookup lookup more coherent with its
SearchVectorExact base which configures its rhs SearchQuery with its
lhs' config.

Hannes Ljungberg 65ab4f9f03 Fixed #31147 -- Added SearchHeadline to django.contrib.postgres. 2020-03-03 15:39:52 +01:00
Simon Charette d0f1c03331 Refs #31211 -- Prevented SearchConfig nesting in SearchVector and SearchQuery init. 
Passing a SearchConfig instance directly to SearchVector and
SearchQuery would result in nested SearchConfig instance.

adamb70 4c6ab1f2aa Fixed #28528 -- Allowed combining SearchVectors with different configs. 2020-02-06 07:52:50 +01:00
Hannes Ljungberg 7edd06a9cf Improved SearchVectorCombinable and SearchQueryCombinable error messages. 2020-01-27 15:09:47 +01:00
James Turk ff00a05347 Fixed #31088 -- Added support for websearch searching in SearchQuery. 2019-12-16 14:59:59 +01:00
Thomasina Lee c38e7a79f4 Fixed #30488 -- Removed redundant Coalesce call in SQL generated by SearchVector. 
Regression in 405c836336.

Simon Charette 405c836336 Fixed #30385 -- Restored SearchVector(config) immutability. 
Regression in 1a28dc3887.

The usage of CONCAT to allow SearchVector to deal with non-text fields
made the generated expression non-IMMUTABLE which prevents a functional
index to be created for it.

Using a combination of COALESCE and ::text makes sure the expression
preserves its immutability.

Refs #29582. Thanks Andrew Brown for the report, Nick Pope for the
review.

Jaap Roes 8a1a919468 Fixed #29997 -- Allowed combining SearchQuerys with different configs. 
Seems to be a needless restriction in
978a00e39f.

Tim Graham 41db8cb252
Used assertCountEqual() in contrib.postgres.search tests. 2018-11-29 14:43:53 -05:00
Claude Paroz f5e347a640 Fixed #27899 -- Added support for phrase/raw searching in SearchQuery. 
Thanks Tim Graham, Nick Pope, and Claude Paroz for contribution and review.

Tom Forbes a3df7574f9 Fixed #29644 -- Made SearchQuery.__str__() reflect negation and grouping. 2018-08-15 16:47:23 -04:00
Simon Charette 1a28dc3887 Fixed #29582 -- Fixed a crash when using SearchVector with non text-fields. 
The PostgreSQL concat() function handles nulls and non-text values better than
the || operator.

Tim Graham 9bea555d06 Fixed test failures due to ordering differences on PostgreSQL 10. 2017-11-15 09:37:18 -05:00
Tim Graham 6b4f018b2b Replaced type-specific assertions with assertEqual(). 
Python docs say, "it's usually not necessary to invoke these methods directly."

Simon Charette cecc079168 Refs #23919 -- Stopped inheriting from object to define new style classes. 2017-01-19 08:39:46 +01:00
Nicola Jordan 978a00e39f Fixed #27143 -- Allowed combining SearchQuery with more than one & or | operators. 2016-09-07 15:26:52 -04:00
Tim Graham 57f76be35e Removed a flaky contrib.postgres search test. 
The test sometimes fails on CI and isn't worth debugging at this time.

Marc Tamlyn 2d877da855 Refs #3254 -- Added full text search to contrib.postgres. 
Adds a reasonably feature complete implementation of full text search
using the built in PostgreSQL engine. It uses public APIs from
Expression and Lookup.

With thanks to Tim Graham, Simon Charettes, Josh Smeaton, Mikey Ariel
and many others for their advice and review. Particular thanks also go
to the supporters of the contrib.postgres kickstarter.
