Three things to check:
- Have your articles got excerpts? The excerpt is weighted above the body, and it is what people see in the results. A members-only article is the exception: it is found by its title and keywords only (see the next answer).
- Do the titles say what the article answers? Titles carry the most weight by far. "Refunds" is a worse title than "How refunds are processed".
- Is the wording the words your customers use? If they say "money back" and you wrote "reimbursement", nothing will match. Put both in.
Still stuck? Ask the developers who wrote it. We aim to reply within one business day.
