The discussion revolves around the feasibility of constructing a search engine for Anna's Archive (AA), focusing on the potential scale and technical challenges involved. Users reference the conversion of large datasets (like Library Genesis) to plaintext and the substantial task of indexing these texts for full-text search capabilities. Key challenges highlighted include data extraction from diverse formats, data cleaning, and the choice of search engine technology, as any poor decision could require extensive reindexing in the future. Additionally, users remark on the existing limited search functionalities of AA, compared to alternatives like Z-Library, while noting the legal concerns regarding the content held within the archive.
