CRM API advanced searchs

Hi,

how can I search in zoho crm modules in an advanced way with API v2 (oAuth).

searchRecords and search methods hava some limitations:

* maximum of 5 criteria
* equals and startsWith conditions

how for example can I make a search with:

somefield not equal "Somedata"

this is an easy example, but, there is no way by API to fetch full queries like in the web environment?

For example, I have found many examples with Creator API with much more options in doing filters.

Thanks in advance.
