Hello again Geert-Jan! What you're trying to do is indeed possible with Solr 4 out of the box. Other terminology people use for this is multi-value time duration. This creative solution is a pure application of spatial without the geospatial notion -- we're not using an earth or other sphere model -- it's a flat plane. So no need to make reference to longitude & latitude, it's x & y.
I would put opening time into x, and closing time into y. To express a point, use "x y" (x space y), and supply this as a string to your SpatialRecursivePrefixTreeFieldType based field for indexing. You can give it multiple values and it will work correctly; this is one of RPT's main features that set it apart from Solr 3 spatial. To query for a business that is open during at least some part of a given time duration, say 6-8 o'clock, the query would look like openDuration:"Intersects(minX minY maxX maxY)" and put 0 or minX (always), 6 for minY (start time), 8 for maxX (end time), and the largest possible value for maxY. You wouldn't actually use 6 & 8, you'd use the number of 15 minute intervals since your epoch for this equivalent time span. You'll need to configure the field correctly: geo="false" worldBounds="0 0 maxTime maxTime" substituting an appropriate value for maxTime based on your unit of time (number of 15 minute intervals you need) and distErrPct="0" (full precision). Let me know how this works for you. ~ David ----- Author: http://www.packtpub.com/apache-solr-3-enterprise-search-server/book -- View this message in context: http://lucene.472066.n3.nabble.com/Modeling-openinghours-using-multipoints-tp4025336p4025359.html Sent from the Solr - User mailing list archive at Nabble.com.
