word_pairs searches for the occurrences of a pair of words in sentences. These words can be separated by intervening strings (viz. other in-between words).

1 2	word_pairs(corpus, word_1 = NULL, word_2 = NULL, min_intervening = 0L, max_intervening = 3L)

`corpus`	A character vector of sentences.
`word_1`	A regular expressions for the first word. The regex must enclose the word with word boundary character (i.e. `"\\b"`).
`word_2`	A regular expressions for the second word. The regex must enclose the word with word boundary character (i.e. `"\\b"`).
`min_intervening`	Number of minimum occurrence of the intervening word. The default is `0L`.
`max_intervening`	Number of minimum occurrence of the intervening word. The default is `3L`. Use `Inf` to get infinite intervening words after `word_1` and before the occurrence of `word_2`.

A list object with the following elements:

pattern: the extracted pattern spanning from the first word to the second word.
pattern_tagged: the version of pattern containing tags for the first and the second word.
matches: the sentence matches containing the word pairs that are tagged for the first and the second word.
