Faceting on tags will give you all the related tags, including the original tag (tagA in your case). You will have to filter out the original tag on the client side if you don't want to show that. With Solar 1.4, you will be able to use localParam to exclude the original tag in the results. If you tags field is analyzed, you will want to facet on a raw copy (using copy field) of the tags.
If you want related tags that starts with ba, you can use a facet.prefix; q=tags:tagA&facet=true&facet.mincount=1&facet.perfix=ab Bill On Mon, Jul 20, 2009 at 2:40 PM, Avlesh Singh <avl...@gmail.com> wrote: > If I understood your problem correctly, faceting on "tags" field is what > you > need.
