CRM API getSearchRecords multiple searchCondition

Does this functionality exist yet?

I really need this, I have seen other posts with this same question.

Please let me know if/when this might be available. We are integrating your CRM with our PBX software. It would be a big drawback if we could not search by multiple fields. Once complete we will be offering this to all our current customers which could bring your company a good amount of business.
