Ticket #102 (new enhancement)
Optimisation for freetext search using regexs
|Reported by:||kjetil@…||Owned by:|
I advocated strongly freetext as a deliverable for the SPARQL WG, but there wasn't enough consensus to get it in. Also, my requirements were pretty simple, and did not require the full XPath/XQuery requirements that many others have. I summarised my requirements in the following advocacy
The WG (amongst them, a certain 4store developer :-) ) noted that these requirements could be met by transforming the search string to a regular expression in the application layer. Indeed it can. However, no engines are optimized for this and it can potential be
much slower than the built-in free text index.
My feature request is thus that the engine optimizes for certain regular expressions
If the user search term is "dahut", then the regular expression boils down to
I hope this is doable.
