Search - no parsing

Hi @mbatz,
Today i crash my app when i try use search in list object.
I wrote text example:

and crash for my case.
if i wrote an example
then show my some results less then all objects
when i use + something do it in search and limit results
this is weird

the same in top search
\p crash app

i hope you fast fix this bug and using other similar special characters in search which can crash app
