[Bug]: oracle text includes string not working as expected

[djpiper28]

What went wrong:

o:"target creature gains protection" does not provide cards with that in the oracle text, however o:/.*target creature gains protection.*/ does.

Expected behavior:

o:/.*target creature gains protection.*/ and o:"target creature gains protection" should provide the same output.

Also occurs with the name:"goblin motivator" which should have the same output as goblin motivator

[djpiper28]

Two cases:

1. o:<WORD>
   i.e: o:opt, the levenshtein difference should used on output of the trie and all cards with greater than 80% matching should be added to the output

2. o:<STRING>
   i.e: opt:"goblin motivator", a lookup for the exact string goblin motivator (monte carlo string lookup) should be done after normalisation. Normalisation being turning everything to lowercase.
