Available filters in the search option:

Examples
Search for words starting by upper case A.
\bA\b corresponds to the limit of the word, note its position regarding the searched character; in this case it stands for the initial limit of the word.
Search for words ending by lower case a.
a\b\b corresponds to the limit of the word, note its position regarding the searched character; in this case it stands for the final limit of the word.
Search for words starting by upper or lower case a.
\b[aA][ ] square brackets indicate the disjunction (a or A) of all the characters they contain. The order of characters is indifferent.
Search for words starting by any lower case vowel.
\b[aeiou][ ] square brackets indicate the disjunction (a, e, i, o or u) of all the characters they contain. The order of characters is indifferent.
Search for words starting by ch (both lower case).
\bch
The characters c and h are searched in the order and position indicated in the RegEx.
Search for words starting by t followed by any lowe case vowel.
\bt[aeiou]
The sub-expression [aeiou] represents a single character that may be any of those indicated within the square brackets.
Search for words ending by an n, preceed by any lower case vowel.
[aeiou]n\b\b, in this case, and because of its position regarding the other characters, represents the final limit of the word, before the limit there is an n, and before the n there is a lower case vowel (any vowel).
Search for words ending by w and containing, in a non-specific place, the characters sequence ng.
\b.*ng.+w\b
The first \b indicates the initial word limit; the . (dot) indicates any character; the * indicates that the previous character may not be, but it may also be indefinite times. In this case, the combination \b.*ng allows to search for words that may starts by one or more characters followed by ng, and simultaneusly allows to search for words starting by ng, that is, ngwith no previous characters.
The sign + (addition) indicates that the preceding character (any, indicated by the dot) must be at least once, but it may also be indefinite times. In this case we use the + because we know that in Mapudüngun there are no words ending by ngw, there must be at least one character between ng and w.
