# lws api test fts
Demonstrates how to create indexes and perform full-text searches.
## build
```
$ cmake . && make
```
## usage
Commandline option|Meaning
---|---
-d <loglevel>|Debug verbosity in decimal, eg, -d15
-c / --createindex|Create an index file, instead of searching
-i / --index <file>|Use this file as the index
The two modes are:
