I've done a few hours of research but I've yet to find the golden answer. This is one of those research topics I find difficult to explain to Google search.

Anyway, my goal is to take a string like below,

Step 1: User searches for, "3 bedroom apartment $2600 San Francisco".

---

Step 2: ?????? Magic happens in this layer ???????

---

Step 3: Intelligent api search string is constructed:

http://api.service.com/?city=San%20Francisco&heading="3 bedroom apartment"|"three bedroom apartment"|"3 bedroom apt"|"three bedroom apt"&min_price=2200&max_price=2800

The magic is Step 2 should be able to handle:

• mis-spellnigs
• Correctly predicts city
• Understands what a number means (if it is currency a.k.a "$3" or "3 dollars" or a value for something).
• Throws out common articles like "and", "the", etc.

Preferably, the solution uses PHP or Javascript asynchronous call to a third-party service I could use to perform the database algorithms and magic (Google??). I'm open to building something with some open-source code that uses my own database too if needed.

Thanks guys for the insight!
