Queries using multi-repeat OR fail

[alex9smith]

Queries using the multi_repeat filter with OR as the method always fail with the same error message shown in #11.

An example:

Python 3.9.4 (default, May 10 2021, 13:51:57)
Type 'copyright', 'credits' or 'license' for more information
IPython 8.2.0 -- An enhanced Interactive Python. Type '?' for help.

FYI @priolap this is now fixed (see #16). If you update to 1.3.3 your queries will work

[priolap]
