I've mislaid the previous search times I had, though I guess some are on
the mailing list somewhere, so I have no concrete figures. I did run
some searches earlier today, the results were generated noticeably
faster than before. Search results were being generated in a time
comparable with a normal page view. Maybe a little slower than when a
page is pulled from cache, but probably a little quicker than when a
page is generated from wikitext.
Thats a really good result. Great work.
I haven't looked at the code, so maybe this is way off the mark.
Would you gain some more improvement by ordering the words and searching
with a non-linear method?
e.g. from your list:
linux 0.010
towel 0.028
angel 0.082
and without knowing other factors (number of results returned, position
in word list) those results suggest a potential 3-8 fold improvement.
Cheers,
Chris
PS. I checked three five letter words at beginning, middle and end of
my index. They each returned exactly one result, no pagenames.
#52 0.122
#888 0.152
#1756 0.153
Those are complete page timings, which would indicate that the impact of
further savings in searching may not be great.
