Christian Hergert: Writing Fast Search

The problem we encountered in my last writing was that gnome-clocks was taking about 300 milliseconds to complete a basic search query. I guess the idea is that if you type “paris” into GNOME Shell you’ll get the time in either Paris, France or one of the Paris’ in the United States. I guess 300 milliseconds wouldn’t be so bad if it didn’t also consume 100% of the CPU during that time.

Thankfully in my career I’ve had plenty of opportunity to work with database search indexes. So I have some practical experience in making that stuff fast(er).

So this morning I put together a small search index which can be generated from the Locations.bin using the libgweather API. That search index contains the serialized document form and a series of trigrams for the GWeatherLocation textual representation. That search index is meant to be static and installed along side Locations.bin.
