I was wondering is there any way to classify a single word before applying a search on elasticsearch. Let's say I have 4 indexes each one holds few millions documents about a specific category.

I'd like to avoid searching the whole search space each time. This problem becomes more challenging since it's not a sentence, The search query usually consists only a single or two words, so some nlp magic (Named-entity recognition, POS etc) can't be applied.

I have read few questions on stackoverflow like:

Semantic search with NLP and elasticsearch

Identifying a person's name vs. a dictionary word

and few more, but couldn't find an approach. are there any suggestions I should try?

Could you be more specific about what you are trying to achieve ? Do you want to perform word classification using elasticsearch or do you have already a solution to classify queries ? – Pierre-Nicolas Mougel Jul 24 '19 at 12:02
@Pierre-Nicolas Mougel I'd like to find a way to classify the query which holds one or two words (I haven't found yet a way to classify queries). – JammingThebBits Jul 24 '19 at 17:17
@JammingThebBits Were you able to find a solution or any workaround? Could you please share it? – Yashwanth Jun 15 '20 at 14:36
@Yashwanth I left it, wasn't able to solve it. – JammingThebBits Jun 23 '20 at 11:17
