Hi ES users,

I'm having issue getting a result when performing wildcard query searching by a char sequence (DNA sequence in my case). It works perfectly for full full-length sequence and with full-length sequence with a leading and ending wildcard. The issue exists only when searching by a sub sequence for which characters were removed from the beginning of full-length sequence.

1. The following query works fine, result is present (full-length sequence with two wildcards):

2. The following query works fine, result is present (part of the sequence removed from the end):

3. The following DOES NOT work, result is NOT present (part of the sequence removed from the beginning):

Any ideas why I'm getting an empty result for 3rd query?

Thanks,  
Krzysztof
