Simon Charette 5637933268 Simplified handling of weights in SearchRank. 2020-02-26 08:16:22 +01:00
Simon Charette 1138ca4c57 Formalized SearchVector and SearchRank signatures. 2020-02-26 08:12:45 +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.
 2020-02-26 08:03:46 +01:00
Simon Charette 3d62ddb026 Refs #3254 -- Removed unnecessary truth check in SearchVectorExact.as_sql(). 
Direct usage of the @@ operator is perfectly allowed.

Thanks Simon Charette for the review.

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.
 2019-05-20 08:34:06 +02:00
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.

Claude Paroz f5e347a640 Fixed #27899 -- Added support for phrase/raw searching in SearchQuery.

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.

Simon Charette 08654a99bb Fixed #28492 -- Defined default output_field of expressions at the class level. 
This wasn't possible when settings were accessed during Field initialization
time as our test suite setup script was triggering imports of expressions
before settings were configured.

Mariusz Felisiak 7724879b52 Removed unused _combine() node argument from various combinable classes.

since its introduction in 2d877da855
(SearchVectorCombinable/SearchQueryCombinable/SearchQuery).

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.
