Hi, On an e-commerce site I want to display the facets from a search so that you don't need to remove a current facet selection before you can select a different one. Once you select an age range (9-12 years for example) the search will return with only the selected age range in the age range facet. I want to display all the possible age range facets (taking account of all the other facets selected) with the 9-12 years selected. To do this I am contemplating reissuing the query for each facet in turn without the filter applied for that particular facet so that I can obtain the list of possible options available for this facet. The problem in doing this is that it will require an extra query for each facet that we want to display. Can I assume that I can maintain acceptable performance by using more servers and issuing the extra queries in parallel? Can anybody think of a less clumsy solution to this? Thanks Tim ---

``` Hi,  If I understood correctly the question, then you can do all with a single search request. Use the range facet to define several ranges and you can get count on them. And have two of those, one that is global (not bounded by the user query) and one that isn't (bounded by the use query). Note that each facet can also have an addition filter to further restrict the docs it will run on.-shay.banon On Saturday, November 20, 2010 at 2:58 PM, Timber wrote: Hi,On an e-commerce site I want to display the facets from a search sothat you don't need to remove a current facet selection before you canselect a different one.

That works a treat.
