Is the "AND" Search Operator Broken?

[neworleans_43]

I get results when searching for 2009 inline thermal or 2010 inline thermal, but when I use the AND search operator to include 2009 and 2010 together I GET NOTHING. I should at least get 2 results, you know?

Search for "2009 inline thermal" works.Search for "2010 inline thermal" works.Search for "2009+2010 inline thermal" DOES NOT WORK!

@neworleans_43,

In the titles of the listings, "on-line" is spelled as two words, but you had it as one word in your search.

eBay search is not truly Boolean. It expands some words, to include other possible spellings, but when you start to get fancy with the search, it can change or limit what expansions are done overall. (FYI, enclosing keywords in parentheses acts as an OR operator, not AND.)

A search for 2009 will not match the keyword late2009 written as one word.

A search for late2009 2010 inline thermal finds those two listings:

Actually, it does, as is shown in OP's first screenshot. Apparently, the search expansion is wide enough to find that listing.

Search expansion can match late2009 under certain circumstances, but when using the Boolean OR search command as in the last example, search expansion is disabled.

Using advanced search commands (quotes, exclusions, or parentheses with multiple keywords separated by commas) will disable search expansion -- therefore no keyword substitution or automatic category navigation occurs, and only literal keyword matches will be found.

Agreed. I said that earlier.
