文本字段中的Solr范围查询

Question

I have a multi valued field. The content looks this way

multi_field:"type:type1; YEAR:2008"

I want to be able to make range requests based on YEAR substring. I cannot understand if I can perform this kind of range queries. I want to have something like this. q=multi_field:"type:type1;*" AND multi_field:"*YEARS:[2005 TO 2010]*"

Is it possible? I know it looks horrible. But is there any way I can get it?

Answer 1

No, it is not possible (at least without a hell-a-lot of coding). The easiest way should be to fix the indexing code to split the field into two separate fields. If you need to keep the original multi_field available (eg it is used in processing the search results), create two new fields (eg multi_field_part1 and multi_field_part2 ), do the search over the new fields ( q=multi_field_part1:type1 AND multi_field_part2:[2005 TO 2010] ), but use the old one in results.
