# Concat [String]

### Description
Given two `[STRING]` inputs, concatenate the strings.

*Caution:* The output's size is `|LEFT| * |RIGHT|`. This can be very large.
See parameters `Take Top N from LEFT / RIGHT`.

### Input
- `LEFT [STRING]`: Left input
- `RIGHT [STRING]`: Right input

### Output
- `RESULT [STRING]`: the combined output

### Parameters
- `Separator`: string to use as a separator between the concatenated strings (Default is a space)
- `Coefficient LEFT input`: Relevance coefficient to apply to `LEFT` (Warning: The sum of the two coefficient should sum up to 1.0)
- `Coefficient RIGHT input`: Relevance coefficient to apply to `RIGHT` (Warning: The sum of the two coefficient should sum up to 1.0)
- `Take Top N from LEFT`: Use only the Top N from `LEFT`. Use 0 for no limit (Default: 0).
- `Take Top N from RIGHT`: Use only the Top N from `RIGHT`. Use 0 for no limit (Default: 10).
- `Make all permutations`: if true, concat both ways - `LEFT`+`RIGHT` and `RIGHT`+`LEFT`
