I have List collection with around 35,000 strings

Typical string looks like this:

"<i>füüs</i>ampri tähis;lüh ld-st<i>anno</i>, aastal;<i>maj</i> lüh pr-st<i>argent</i>, raha (kursisedelitel)"

Basically this string contains bunch of words in Estonian 🙂

I need to allow user to perform RegExp search on 35,000 strings

If I perform search using /ab.*/ expression, then search takes less than a second

If I perform search using /.*ab/ expression, then search takes around 10 seconds

My question is: How can I make second search faster (less then 1.5 seconds)?

Thank You very much
