The above configures a synonym filter, with a path of analysis/synonym.txt (relative to the config location). The synonym analyzer is then configured with the filter. Additional settings are: ignore_case (defaults to false), and expand (defaults to true). The tokenizer parameter controls the tokenizers that will be used to tokenize the synonym, and defaults to the whitespace tokenizer. Two synonym formats are supported: Solr, WordNet.

About 10 percent of a cat's bones are found in the tail, allowing the cat tremendous range in how it moves its tail. While the tail does serve as a rudder for balancing, communication with humans and other cats often takes place nonverbally.
Five-lined skinks and slender skinks have also been used in studies of tail loss as an antipredator mechanism. Like many other lizards, skinks can voluntarily release the tail when it is seized by a predator. Skinks often move or wave their tails in order to direct predators away from their bodies.
