Description

Alphanumeric text is getting indexed separately for the WhitespaceTokenizerFactory. I have tried tokenizer class solr.KeywordTokenizerFactory too but still my text getting splitted and indexed.

Scenario
Input string: ABCD1234EFGH
Generated index: ABCD, 1234, EFGH
Expected index: ABCD1234EFGH

Search
Input: ABC* returns success
Input: ABCD123* returns fail (success expected)
Inout: ABCD1234 returns success
