How Can I Improve the Relevancy of My MySQL Fulltext Search Results?

Improving MYSQL Fulltext Search Result Relevancy

In MYSQL, performing fulltext searches using MATCH(...) AGAINST(...) offers a more robust approach to finding relevant results compared to using LIKE operators. Unlike LIKE, which simply checks for character sequences, fulltext search utilizes an underlying index and linguistic analysis to identify matches based on relevance.

Using MATCH(...) AGAINST(...):

Replace your existing query with a fulltext search query as follows:

$query = "SELECT * FROM `vocabulary` WHERE MATCH(translation) AGAINST('word')";

Matching Scores:

The MATCH(...) AGAINST(...) expression returns a matching score for each row in the table. A higher score indicates a more relevant match. By default, MYSQL sorts results by this score in descending order (most relevant first).

Example Output:

Using the modified query above, you should now see the results sorted by relevancy:

1 | word <- exact match
2 | crossword <- partial matches sorted by matching score
3 | words
4 | wordsmith

By utilizing fulltext search with MATCH(...) AGAINST(...), you can effectively prioritize the display of exact matches and rank partial matches based on their relevance.
