Hi. We have a large index (~ 28 GB) which is distributed in three different directories, each representing a country. Each of these country wise indexes is further distributed on the basis of last update date into 21 smaller indexes. This index is updated once in a day.
A user can search into any of one country and can choose last update date plus some other criteria. When the server application starts, index readers and hence searchers are created for each of the small indexes (21 x 3) and put in an array. Depending on the option (country and last update date) chosen by user we pick the searchers of correct date range/country and create a new ParallelMultiSearcher instance. Now my question is - can I use single filter (caching filter) instance for every search (may be on different searchers)? =================================================================================== e.g for first search i create an filter of experience 4 years and save it. if another search for a different country (and hence difference index) also has same experience criteria, i.e. 4 years, can i use the same filter instance for second search too? i have tested a little for this and surprisingly i have got correct results. i was wondering if this is the correct way. or do i need to create different filters for each searcher (or index reader) instance? Thanks in advance. -- Regards, Samar
