Andrew White	c5015d77e2	Allow k to be higher than doc size in max_marginal_relevance_search (#1187) ... Fixes issue #1186. For some reason, #1117 didn't seem to fix it.	1 year ago
Tom Bocklisch	47c3221fda	Max marginal relecance search fails if there are not enough docs (#1117) ... Implementation fails if there are not enough documents. Added the same check as used for similarity search. Current implementation raises ``` File ".venv/lib/python3.9/site-packages/langchain/vectorstores/faiss.py", line 160, in max_marginal_relevance_search _id = self.index_to_docstore_id[i] KeyError: -1 ```	1 year ago
seanaedmiston	f0a258555b	Support similarity search by vector (in FAISS) (#961) ... Alternate implementation to PR #960 Again - only FAISS is implemented. If accepted can add this to other vectorstores or leave as NotImplemented? Suggestions welcome...	1 year ago

dham	e04b063ff4	add faiss local saving/loading (#676) ... - This uses the faiss built-in `write_index` and `load_index` to save and load faiss indexes locally - Also fixes #674 - The save/load functions also use the faiss library, so I refactored the dependency into a function	1 year ago

Harrison Chase	2163d064f3	add return of ids (#254) ... not actually sure the desired return in add_example to example selector is actually general/good - whats the use case?	2 years ago
Xupeng (Tony) Tong	bb4bf9d6d0	chore: minor clean up / formatting (#233) ... to get familiarize with the project	2 years ago
Samantha Whitmore	09f301cd38	Add add_example method to all ExampleSelector classes, with tests (#178) ... Also updated docs, and noticed an issue with the add_texts method on VectorStores that I had missed before -- the metadatas arg should be required to match the classmethod which initializes the VectorStores (the add_example methods break otherwise in the ExampleSelectors)	2 years ago
Samantha Whitmore	315b0c09c6	wip: add method for both docstore and embeddings (#119) ... this will break atm but wanted to get thoughts on implementation. 1. should add() be on docstore interface? 2. should InMemoryDocstore change to take a list of documents as init? (makes this slightly easier to implement in FAISS -- if we think it is less clean then could expose a method to get the number of documents currently in the dict, and perform the logic of creating the necessary dictionary in the FAISS.add_texts method.
