improve search

[nick1udwig]

problem

currently search is keyword search

however, agents will often plug in a variety of keywords -- and since not all of them match, the search returns null

see eg

{
  "id": "toolu_01NapDi9mJdgdn3GCkcxjaox",
  "tool_name": "hypergrid_search",
  "parameters": "{\"query\":\"cryptocurrency market crypto bitcoin ethereum price trends\"}"
}

{
  "tool_call_id": "toolu_01NapDi9mJdgdn3GCkcxjaox",
  "result": "{\"content\":[{\"text\":\"[]\",\"type\":\"text\"}]}"
}

whereas a query for just cryptocurrency or crypto would give a hit

possible solutions

1. improve tool description to tell agent to use a single term
2. improve actual querying so this kind of search is supported
3. vector search (2++)
