Hi ES folks,

Hope everyone is doing fine. I am facing a problem when querying data containing mathematical expressions. For example I have following data indexed in my ES

- what is 3+4
- what is 3-4
- what is 3\*4
- what is 3/4

when I try to search for **what is 3+4** the first response comes out to be **what is 3\*4** the actual result is 3-4 in the response list.

I am using an Arabic analyzer for indexing and searching. I have googled and tried a couple of analyzers but no luck. any help would be appreciated.

Hi @Hassan_zaib_Hayat

Do you use arabic analyzer for english text?  
I would try some tests with the whitespace analyzer.  
It will not remove the operators, "+ - \*", like other analyzers.
