Tag separator
This is the character that separates a word from its tag in your corpus. For example, if your corpus looks like the following:
que;conj
era;v_imp_0s
de;prep
ventanas;n_fp
hacia;prep
la;art_fs
To search for any preposition, you would search for:
\w+;prep
This is helpful because it allows you to view your search results with their tags or without them.
Note: Keep in mind that if your tag separator is one of the regular expressions reserved characters, then you must use the escape character to take that into account. For example, if words in your corpus are separated by ^, then you would place the escape character before it to let the search engine that you don't mean to use a regular expression character. In this corpus:
que^conj
era^v_imp_0s
de^prep
ventanas^n_fp
hacia^prep
la^art_fs
To search for any preposition in this corpus, you would search for:
\w+\^prep
The special characters are:
\ ^ $ { } [ ] ( ) . * + ? | - &
