Enable searching from the middle of the word?

Reason: For technical terms, people may not remember the full name, but only parts. Searching parts in the middle of a long string does not show result.

Screenshots:

1. search full term or prefix works:

2. Search part term does not show any result:

Just for comparison, the algolia search engine seems to support such use case:
