Hi Erick, Thank your for your thoughts, I had exactly the same idea like your screenLCD suggestion (but with a semicolon) For example: range1 range2 range3 range_flags properties 80000 90 2001 range1;km, range2;kw, range3;year group;auto, make;audi, model;a4, color;red 50000 75 2003 range1;km, range2;kw, range3;year group;auto, make;nissan, model;primeria, ABS 40000 75 2004 range1;km, range2;kw, range3;year group;auto, make;nissan, model;primeria, ABS 4 null null range1;rooms group;immo, type;flat 16 null null range1;memory group;handy, make;iphone, model;3GS, memory;16GB
The range_flags column will describe the range1, range2, range3 columns so that you can do queries like: q=*:* fq=properties:group;auto fq=range_flags:range1;km fq=range1:[20000 TO 80000] The range_flag filter is not absolutely nessasary, but it ensures that you do range queries on the data you intent to.
