Although it doesn't appear to say so in the doc page, intitle
expects an exact phrase, not a list of words.
You can currently see this by:
/2.2/search?intitle=get column array&site=stackoverflow
which currently returns one result with that exact phrase in the title, but doesn't return the many questions that have those 3 words in other arrangements.
To search for titles that contain a list of words,
use the /search/advanced
route and pass multiple title:...
properties in the q
parameter.
For example:
/2.2/search/advanced?q=title:get title:column title:array&tagged=javascript&site=stackoverflow
which currently returns the question you expect as well as 5 other valid results.
