# Concat [Obj,String]

### Description
Given two `[OBJ,STRING]` inputs, concatenate the strings per matching object.

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

### Output
- `RESULT [OBJ,STRING]`: the combined output
- `STRINGS [STRING]`: only strings

### 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)
- `Combination`
  - `Disjunctive`: objects must occur in at least 1 input (default)
  - `Conjunctive` : objects must occur in all inputs
- `Make all permutations`: if true, concat both ways - `LEFT`+`RIGHT` and `RIGHT`+`LEFT`
