Solr：如何在文本字段中搜索完整匹配？ 是否有隐藏的equal（）运算符？

Question

it is too simple to describe:

q=mydynamicfield_txt:"video"

I want only hits when mydynamicfield is exact "video. Other way round, how to supress hits, where "video" is only part of the field (like "home video").

Is this supported with Solr3.1 out of the box, or do I have to add my own special brackets like "SOLRSTARTSOLR video SOLRENDSOLR" in my index, to retrieve later my term between "START" and "END". Kind of manual regex anchoring.

This is PITA cause it needs special handling in index/gui and breaks highlighting.

Where is the way to go?

Answer 1

One solution to create untokenized(KeywordAnalyzed) field and search within it - all your text will be distinct token in Solr index. Other solution is to write filter which will read token count from index and compare to query tokens ie filter entities where doc_tokens > query_tokens assuming that all query tokens are matched.
