You don’t need to know the target queries, if you compute embeddings of your entries and your query you just find which embeddings are closest to your query embedding. The advantage over using synonyms is that the embedding is meant to encode the meaning of the content such that similar embeddings represent similar meaning and you won’t need to deal with the combinatorial explosion of all the different ways you can say the same thing with different words (it can also work for other content, like images, or multi language if ur network is trained for it).
