##### Locale-Insensitive Fixed Pattern Matching in stringi

String searching facilities described in this very man page provide a way to locate a specific sequence of bytes in a string. Fixed pattern search engine's settings may be tuned up (for example to perform case-insensitive search), see the stri_opts_fixed function for more details.

##### Byte Compare

The Knuth-Morris-Pratt search algorithm, with worst time complexity of O(n+p) (n == length(str), p == length(pattern)) is utilized (with some tweaks for very short search patterns). For natural language processing, however, this is not what you probably want. It is because a bitwise match will not give correct results in cases of:

1. accented letters;

2. conjoined letters;

3. ignorable punctuation;

4. ignorable case,

Note that the conversion of input data to Unicode is done as usual.
