update text search to mixed text and numbers search

[bartman081523]

this patch should give the ability to search easier for links in the text. instead of typing all the text you can also add numbers as a representation for the text you want to add (refine)

e.g.

`search abc

maybe 12 or the phrase for the sum 12 appears as an sub-result

`search abc 12

maybe 24 or the phrase for the sum 24 appears as a sub-result

`search abc 12 24

---

can you please test before merging? on my side it runs. test with

use conversions
search abc 6 12

it should search for sum 24
