Known issues

This page describes issues where FQL functions do not behave as intended in various situations. These are all issues that we intend to fix, but the solutions may take some time.

Dates and Times

  • We claim support for ISO 8601 time and date formats, but the library that we use does not, in fact, support all variations of ISO 8601.


  • The Join function does not behave well with reversed indexes. You might try using Union instead.

  • When you attempt to Paginate a set composed with one (or more) of the set functions, such as Intersection, an estimator uses the page size to guess how many items to fetch from the set for manipulation. When the page size is too small to reach far enough into the set, the result may contain far fewer entries than expected. Increasing the page size can often improve the results.
