Hi There I would like to have some help on how to do some things with elastic search. I have an index with a lot of products that came from some websites (parsed by a web crawler). I would like to show to my user some filters, so he can refine his search. I tried to use termFacet on product name, but it is returning some terms that I don't want to show in the filter. What is the best approach to do this? Is there a way to query how many know terms I have in a search result? Sorry if this doubt is too basic, I don't know where to ask this. Any help is appreciated! Thanks in advance Marco Silva ---

Hi Radu Thanks for the reply! Let me try to explain with an example: When user search for car, I would like to show filters like: mbw (3) ford (5) ferrari (1) The problem is I don't know the car brand, I just have the name and a description. If I put a termFace on name or description, it can return other therms that are not brands... like wheels or some other word that is common for all cars... right? What I want to do is, from a list of pre defined brands, know the number of each on the search result... Is a good aproach ti create a termFacet for each brand, with a filter on it (to limit to the brand name)?

well, ElasticSearch cannot do the guess work for you so you'll need to extract the brand name yourself (from your predefined list - its easy). then feed it into a brand field ... Does this help? Peter. ---

Hi Peter This is what I want to know... is this the right way to do this? Get the list of terms and see if it is a predefined brand? I'm afraid I have only one document for one brand, and this term could not be returned right? Sorry, I have never worked with lucene or elasticsearch before, things are not clear to me 😉 Thank you Marco On Tue, Mar 6, 2012 at 5:25 AM, Karussell [tableyourtime@googlemail.com](mailto:tableyourtime@googlemail.com)wrote: > well, Elasticsearch cannot do the guess work for you so you'll need to > extract the brand name yourself (from your predefined list - its easy). > then feed it into a brand field ... > > Does this help? > > Peter. ---

Hi Marco, I'm too much of a noob to tell you if there's a right way to do this, unfortunately. What I would do is to define one filter facet for each brand in the predefined list. Then I would run the query with all the facets there. A bit more on filter facets here: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.
