Improve pictogram search

[RodriSanchez1]

Currently, we are using the ARASAAC API's "beast search" endpoint by default to search for images, which returns the best pictograms based on the searchText.

Main Problem:

Occasionally, the API returns a 404 Not Found, resulting in an empty image being associated with a tile.

Edge Cases:

• The issue often occurs when the search text contains a non-infinitive verb. For example:
  Searching for "brushing teeth" results in a 404 error. However, searching for "brush teeth" returns a successful response.
• Plural words

Possible Solutions:

• Modify the search prompt to implicitly return verbs in their infinitive form.
• Add a fallback mechanism when a 404 error is encountered. Options include:
  • Searching alternative symbol sets in GlobalSymbols.
  • Using ARASAAC’s "search" endpoint instead of the "beast search" endpoint. If "beast search" is used, define a maximum number of images to avoid retrieving an excessive amount.
