Facing issue while searching on string type field

Question

I am facing issue in Solr search. My schema is as follows

Answer 1

You need to use the text field type since you intend to search the tokens:

To be specific for Tarun Nagpal <tarunn@abc.com>:

A string field will answer == equality and wildcard queries like *un Nagp*, *unn@abc.com> and even more apparently exotic queries.

A text field will answer to the tokens tarun, nagpal, tarunn abc and com.

Other field types implementing N-gram and Soundex can even correct your spelling.
