Filter and data sorting

I am in problem, i want a list view search bar to search similar data,
i have already tried text box to search using contain text piece but working of that is very slow.
If anyone is can develop an extension then it will be very useful for me and community too…
If any one will develop then i can pay him up to $7.

or
any one can explain working of this type of sorting/filtering

Since solution for faster searching was proposed by @Taifun, I believe you should change topic category to #marketplace because you need a developer to make an extension for you

got it, but SQlite is becoming very complicated for me…
Now, i am looking for someone who can create a aia. for searching data using SQlite…
