How to include the hyphen in the search pattern

We want to be able to search for string patterns that include the hyphen symbol like the following example:

“…Despite its fearsome reputation, the T–Rex was actually quite slow, with a top speed of around 20 miles per hour…”

A search that includes a hyphen in the search pattern is not supported in the default configuration of DocFetcher. For that we need to configure DocFetcher in the following way:

• Remove all indexes
• Set the [word segmentation] option to “Source Code”:

• Recreate all indexes again

Now you can search and find a text pattern that includes a hyphen.

Searching a string pattern inside a longer string

Let’s assume we want to search for the string pattern travel inside a longer string like myblog.cheaptraveling.blog

To achieve that you can use both of the following queries:

*travel*

or

content:*travel*

Including special characters in search patterns

According to the following discussion in the official DocFetcher discussion forum as of 2017-11-17 DocFetcher was not designed for searching for special characters:
