Description

The requests with $search in $expand, e.g. /Shop(1)?$expand=Items($search=a3b) fail with
The URI is malformed. Exception when searching for alpha-numeric strings, containing BOTH letters and digits.

The same $serach, however works fine when applying $search on a root entity.

The issue is caused by the fact that:

1. There are 2 different URI search tokenizers, one for root search, another for expand;
2. The root search parser/tokenizer allows searching strings containing both digits and letters, the second one allows either ONLY letters OR digits.

The issue was fixed by allowing the expand search tokenizer to reuse the functionality (allowed characters) of the root parser.

The patch file with bug fix is attached.
