Lucene IndexReader Exception breaking search #230

Closed jpguillebaud closed 3 years ago

Occasionally the search results on our Umbraco website will break, requiring a restart of the App Service. The following exception is logged whenever this occurs:

This same issue was fixed in Examine 1.0 however we are already using a version later this this as follows. This website is hosted on Azure PAAS and these are the versions of the assemblies:

Umbraco version = 8.6.3.0 Examine version = 1.0.3.0

Can you please help fix this recurring exception?

Please update to the latest Examine version, there's several releases and fixes since the version you are using, see https://github.com/Shazwazza/Examine/releases. I believe this is fixed but feel free to re-open if this is still an issue with the latest version.
