Links Search Bug

We want to support use cases #1-#3 below. #1 is not supported currently.

We have a doc in the links index with this value for 'domains':

"domains":["DOMAIN_END moremags com DOMAIN_END","blog buzzsumo com DOMAIN_END","chameleonartproducts com DOMAIN_END"]

1) User wants to search for all docs that link to any page in chameleonartproducts.com

Query generated right now:

{:query_string=>{:query=>"\"DOMAIN_END chameleonartproducts com DOMAIN_END\" OR \"DOMAIN_END DOMAIN_END chameleonartproducts com DOMAIN_END\"", :fields=>["domains"], :phrase_slop=>0}

This returns 0 results, even though the doc above matches it. It contains "chameleonartproducts com DOMAIN_END"
Expected: return 1 result

2) User wants to search for all docs that link to any page in blog.buzzsumo.com

Query generated right now:

{:query_string=>{:query=>"\"blog buzzsumo com DOMAIN_END\" OR \"DOMAIN_END blog buzzsumo com DOMAIN_END\"", :fields=>["domains"], :phrase_slop=>0}

This returns 1 result, which matches our expectations.

3) User wants to search for all docs that link to any page in www.buzzsumo.com only.

Query generated right now:

{:query_string=>{:query=>"\"DOMAIN_END buzzsumo com DOMAIN_END\" OR \"DOMAIN_END DOMAIN_END buzzsumo com DOMAIN_END\"", :fields=>["domains"], :phrase_slop=>0}

This returns 0 results, which matches our expectations.
