Selection of month "08" and day "01" would be:
date_text:????-08-01*
Or if you wanted month "08" OR day "01":
date_text:????-08* OR date_text:????-??-01*

Thank you for your great suggestion. That worked! A follow-up: We're using
this to do partial date searches on the copyField text field, providing
month "08" and day "01":
date_text:08* AND date_text:01*
It returns the results correctly, but is there a more efficient way to do
this? Thanks.
Warm regards,
Alex

Wildcard patterns work on dates if they are "string" fields.
If your dates are "trie" dates (the default "date" field type now), you
would need to do a copyField to a string field to do the wildcard match.
Examples:
????-05-12*
2010-??-12*

Hi. We're using Solr 4.0Beta and wondered how we can perform partial date
searches. For example, we have this date stored in the index:
<date name="my_date">2010-05-12T00:00:00Z</date>
The user may want to search on all documents from 05-12 without providing
the year. Or the user may want to search on 2010-xx-12 where the day isn't
known but the month and year are known. Is this possible? Is there a sample
search we can run in the admin interface against our index? Thanks.
