TagSaver: Normalizing Tag Storage for Better Filtering
An extras spotlight on TagSaver and the broader idea of moving tag data into proper indexed tables instead of storing comma-separated values in one TV field.
Tag filtering in older Evolution CMS projects was often implemented by storing many comma-separated tags in one TV value and then filtering with LIKE %tag%. That works until it becomes slow, imprecise, and difficult to scale.
The donor idea
TagSaver moved tag handling toward a more normalized model: a table for tags and a relation table linking resources to tags, optionally with TV-aware context.
Why this is better than one comma-separated string
- exact tag matching becomes possible
- filtering gets faster with proper indexes
- partial substring false positives disappear
- multi-TV tagging strategies become easier to reason about
This is one of the better examples of an extra solving not just a UI problem, but a data-model problem that directly affects search quality and filtering performance.
