Edamam recipe search returns empty results for common ingredient: query error fix

Fixes Edamam recipe search calls that return empty results for a common ingredient. Use when the API call succeeds but the hits list is empty and the same ingredient returns recipes in a plain test query. Not for an authentication failure or a quota error, which return an error status instead of empty hits.

Reproduce with the simplest possible call: one common ingredient as the query, no diet, health, cuisine, or meal filters, and a small result window.

Check how the ingredient text is sent: spaces and multi word ingredients must be URL encoded as a single query value, and the query must not carry surrounding quotes or a trailing operator word.

Add the filters from the failing call back one at a time, running the call after each addition.

Check the result window parameters on the failing call: a from offset beyond the total count returns an empty page even when matches exist.

Compare the app id and key environment: a development credential against the production endpoint, or the recipe search plan without a filter the call relies on, can silently narrow results.

Fix the identified filter or parameter in the app, then rerun the original failing search.
