Simple Storage Network framerate drop when searching item descriptions

[ChrisLane]

Describe the bug
When searching my Simple Storage Network for descriptions on vault items, the game does a lot of processing and my framerate drops.

For example, when I search for "#shovelling" to look for shovelling jewels, the framrate drops.

To Reproduce

1. Put lots of items in a Simple Storage Network, including lots of vault items and Jewels
2. Search for a description term that appears in vault items e.g. "#shovelling"

Expected behavior
The framerate should not drop when searching vault item descriptions.

Screenshots or Crash Report
Here's a snapshot I got while using a CPU profiler. It looks like a significant portion of CPU time is spent compiling regex patterns. If possible, this should just be done once.

Here's a snapshot exported from VisualVM:

Info (please complete the following information):

• World Type: Server
• The_Vault Version 3.8.0.1681

Additional context
This doesn't happen when searching items that are not from 'The Vault'.
