[TYPO3-Solr] Using "less than", "greater than" filters with facets

[Søren Malling]

Hi!

Once again totally amazed by the SOLR implementation!

I'm trying out some "facets fun" and created my own type, listed on the 
search page in minutes! Sweet stuff!

Now, I was wondering how I can use these facets more dynamic.

In the example I'm indexing a bunch of products which of course have a 
price (this could be a course with a max number participiants for 
reference). I have indexed my price with a SOLR_RELATION like this

             price_stringM = SOLR_RELATION
             price_stringM {
             	localField = prices
             	multiValue = 1
             }

one product can have multiple prices, there for a SOLR_RELATION

My facet is defined like this

	price {
		label = Maximum price
		field = price_stringM
	}

and shows my indexed prices. One of the prices is "180.00". When 
clicking that I add a filter to the query, but I also products where the 
price is "225.00".

Is it in some way possible to expand the filter through TypoScript or 
the syntax query so I my request to the SOLR server would be like this 
(in human readable language)

Clicking "180.00" would make a request like this -> "Return all items 
where the indexed price field is {max,min,exact} the value 180.00"

FYI, I'm running latest TER version

Thanks a ton and have a nice weekend!

Regards

Søren
