Solr Search is not working as expected after migrated Hybris 5.5 to 6.3

Solr Search is not working as expected in solr cloud mode .When I searched with a product code "10445456" its giving me "684" results instead of giving me one. when I ran the query in solr admin its giving me one result.I have commented the below line in builder class. addFreeTextQuery(searchQuery, field, value, "~0.9", boost / 4.0D);

Below is my solr Log when I search with this term "10445456" and I could see "++OR++" in the below query Normally it comes like this "+OR+".Please give me suggestion how to get rid of this issue.
