I have implemented the solr search on my wiki using the SolrStore extension. I used the filter based search feature of the Solr. One of the filters in the search is the year input. For now, the year input is a dropdown (user can select a particular year and search for results in that year). I want to change it to a range ( where user can select a group of years, say from a to b, to search for results in those years. How cam I achieve this? Thanks in advance. Palash
