Does Sphinx (or other third party) search engine work in my case or should I create my own?

I am creating a search function of my classifieds on my website. Here is some of the criteria I need to meet:

When searching for 'bmw 520' only matches where these two words come in exactly this order is returned. not matches for only 'bmw' or only '520'.
When searching for 'bmw 330ci' results as the above will be returned, but, WITH AND WITHOUT the ci extension. There are a nr of extensions in cars as you all know (i, ci, si, fi etc).
I want the 'minus sign' to 'exclude' all returns containing the word after the sign, ex: 'bmw -330' will return all 'bmw' results without the '330' ones. (a NOT instead of minus sign is also ok)
all special character accents like 'é' are converted to their simple values, in this case 'e'.
list of words to ignore completely in the search string.

Would I need Sphinx or should I write this in a php file?

What do you suggest I do?

Thanks

I think that Sphinx matches all of your criteria.

I think Sphinx is pretty good match to what you want to do, but some things won't happen automatically...

To match on two words together exactly, you either need to use the phrase match mode, or group the words in double-quotes while using the extended match mode.
This is the tricky one - unless you specify specific exceptions, I don't think you can index 330ci as both '330 ci' and '330ci'.
As long as you're using boolean or extended match modes, then the minus sign works as you'd like.
'Special' characters can be converted to standard ASCII, but this doesn't happen by default. You need to set up your charset_table value. This blog post is aimed at Thinking Sphinx (a Ruby plugin for Sphinx), but the setting value is just passed straight through to Sphinx.
You can only ignore specific words on a per-query basis if you've got at least one other word in the query (that is: "-foo" will fail for Sphinx, but "foo -bar" is fine). It's worth noting that you can choose to not index specific words.
