The text_en Analyzer has stemming enabled. You can observe its behavior by
running the following AQL query:
RETURN TOKENS("vegetable", "text_en")
You will see that it stems the word to "veget". Your query compares the
stored value "veget" to the string "vegetable", which will not match the
document.
You should get a match if you use ANALYZER(doc.type == "veget", "text_en").
If not, then verify that the type field is actually indexed with the
text_en Analyzer in the View definition.
To apply the same transformation to the search phrase as to the stored
value, you can do:
ANALYZER(doc.type == TOKENS("vegetable", "text_en")[0], "text_en")
Also see
https://www.arangodb.com/docs/stable/arangosearch.html#searching-for-tokens-from-full-text
Note that ANALYZER() specifies the Analyzer for doc.type but doesn't affect
TOKENS().
To search for more than the first token from the search phrase
(AND-combined), you can use:
ANALYZER(TOKENS("healthy vegetable", "text_en") ALL IN doc.type, "text_en")
Also
see https://www.arangodb.com/docs/stable/arangosearch-fulltext-token-search.html
You may also create a custom text Analyzer with stemming disabled, if that
fits your use case better. See the examples of
