I am working on Solr 4+.
I have several fields into my solr schema with different solr field types.
Does the search on text field and string field differs?
Because I am trying to search on string field (which is a copy field of few facet fields) which does not work as expected. The destination string field is indexed and stored both.
However, when I change destination field which a text field (only indexed), it works fine.
Can you suggest why this happens? What is exactly the difference between text and string fields in solr in respect to searches?
TextFields usually have a tokenizer and text analysis attached, meaning that the indexed content is broken into separate tokens where there is no need for an exact match - each word / token can be matched separately to decide if the whole document should be included in the response.
StrFields cannot have any tokenization or analysis / filters applied, and will only give results for exact matches. If you need a StrField with analysis or filters applied, you can implement this using a TextField and a KeywordTokenizer.
A general text field that has reasonable, generic cross-language defaults: it tokenizes with StandardTokenizer, removes stop words from case-insensitive "stopwords.txt" (empty by default), and down cases. At query time only, it also applies synonyms.
The StrField type is not analyzed, but indexed/stored verbatim.
