I'm unhappy with my current full-text search for semantic retrieval

Got it — “full-text search” often feels blunt for semantic retrieval.
A few common reasons it disappoints:
- it matches keywords, not meaning
- it struggles with synonyms and paraphrases
- ranking can be noisy when terms are common
- it doesn’t handle long documents or nuanced intent well
If your goal is better semantic retrieval, typical upgrades are:
-
Hybrid search
- Combine keyword search with embedding-based vector search.
- This usually gives the best practical results.
-
Chunking
- Split documents into smaller semantic chunks instead of indexing whole docs.
- Improves recall and ranking precision.
-
Embeddings + reranking
- Use vector search to fetch candidates.
- Then rerank with a cross-encoder or LLM-based scorer.
-
Query understanding
- Expand queries, detect intent, normalize entities, and use synonyms.
-
Metadata filtering
- Apply filters like date, product, language, author, source before ranking.
-
Evaluation
- Measure retrieval quality with a test set of real queries.
- Often the issue is less the index and more the lack of tuning/evaluation.
If you want, I can help you choose a better architecture based on:
- your data type
- corpus size
- latency requirements
- whether you need exact keyword matches
- what search stack you’re using now
If you share your current setup, I can suggest a concrete replacement plan.
