Filtering by account id

[Dima101010101]

Hi guys, quick question:
I have stats for users that have unique account ids. I want to search events registered only to specific group of accounts. For example, if I have 1,000 account ids (each constructed out of 7 digits), I want to display results for account ids below certain value.

Now I have search query that displays all of them. When I add "field < value" to the query, splunk shows me message "No results found". By "field" I mean specific word, in my case it's "account_id", and by "value" I mean specific number of account that I want results below it (for example I want results for accounts below 1085382). So only by adding this search parameter I receive no results. What should I do?

Thank you for your help.

Still nothing.
The most interesting part is, that when I do search for specific id: where account_id = 1085382, I receive proper result only for this ID. But if I try more or less with < > signs, there is nothing.
Any other parameters that can do "more/less than" search?
