| Error generating []-shingles | shared | gen_shingles() | |
| Error running reclustering algorithm | k_means_clusterer | lines 56-58 | |
| Error saving result to file(s) | bm25, k_means_clusterer | write_to_file(), write_to_files(), write_to_file() | |
| Error saving to database [] | tfidf, min_hash | insert_inverted_index(), insert_shingles() | Make sure processed/shingles.db exists. |

The following is a list of potential error messages, function calls that throw them, and troubleshooting ideas for minHashModule.c and minHash.c.
| Error Message | File | Function | Troubleshooting |
|---|---|---|---|
| Error running MinHash algorithm | minHashModule.c | minHash() | An error has occurred somewhere in the minHash() function in minHash.c. Ensure all SQL queries in minHash.h run properly on the processed/shingles.db database. |
| Error opening database [] | minHash.c | sqlite3_open() | Make sure the database shingles.db is in the processed/ directory and you can open it using sqlite3. |
| Preparation failed: [] | minHash.c | sqlite3_prepare_v2() | Make sure SQLite3 is functioning and that the SQL queries in minHash.h run properly on the processed/shingles.db database. Search the SQLite3 error message on Google for more information. |
| If the troubleshooting section doesn't help, please submit all relevant information to the issues page. |
