You can try an experiment that automatically enriches drafts of materials papers, patents, lab notes, and datasheets with material name synonyms, chemical formula variants, process names, equipment names, and measurement conditions. If a standardized keyword field is added to each record being searched, performance can change even with existing BM25 or simple vector search.
This may be especially useful in laboratories or company environments where a legacy search system already exists. Before fully introducing a new indexer, the burden-light way to validate it is to compare recall and post-search noise ratio before and after enrichment.
