Search List - Keyword Phrases Returning Less Results

[adam-hurwitz]

Expected

Adding a keyword phrase with the OR operator | in the YouTube API v3 search list request should return more results than without a keyword phrase because OR is inclusive.

ie: cryptocurrency|DigitalCash|digital+cash|dash is passed via the q parameter, and is expected to return at least the same or larger size JSON response of videos compared to the search without the keyword phrase such as cryptocurrency|DigitalCash|dash.

Documentation

The YouTube Search: list documentation does not mention keyword phrases explicitly for the q parameter.

Your request can also use the Boolean NOT (-) and OR (|) operators to exclude videos or to find videos that are associated with one of several search terms. For example, to search for videos matching either "boating" or "sailing", set the q parameter value to boating|sailing. Similarly, to search for videos matching either "boating" or "sailing" but not "fishing", set the q parameter value to boating|sailing -fishing. Note that the pipe character must be URL-escaped when it is sent in your API request. The URL-escaped value for the pipe character is %7C.

Implementation: Search Requests documentation mentions keyword phrases with the skateboarding+dog example, which is the syntax followed below using + in between keyword phrases' words.

Did YouTube API v3 pull test as a function of number of OR Boolean operators. The number of search hits increase with 1st and 2nd uses of OR (hit results: text1 < text1 OR text2 < text1 OR text2 OR text3), but using three or more OR statements, the hits begin to tail off as more OR operators are used for a given pull. Thus, in my analysis, using two OR operators gives max (non-duplicate) results for each pull. Curious why YT does this.
