My stored procedure text search is buggy - tsql

Question

I'm stuck - I have this nice little text searcher I've put together.
I realised I needed to count lnies in individual blocks of text that the stored procedure is stored in, so I think I've figured a way to do that.
But it's not getting every instance of a search term in a stored procedure - and I think it's the same reason... the search term is split across a text boundary.
I've looked at how to change my query - and I'm coming up blank. The skills involved to change it are beyond me!

Your where clause seems to have an issue, this bit here
(
(CHARINDEX(#searchString, SC.text) > 0
AND CHARINDEX(#doesNotContain, SC.text) = 0)
--OR
--(SO.type = 'U'
--AND CHARINDEX(#searchString, SO.name) > 0
--AND CHARINDEX(#doesNotContain, SO.name) = 0)
