The point of it…
is to home in, for example, on the ones in L1 or R1 position. To find sub-patterns of collocation, so as to more fully understand the company your search-word keeps.
Here the collocates of COULD in some Jane Austen texts show how negatives crop up a lot in R1 position.
How to do it... just press the header
The frequency-ordered collocation display can be re-sorted to reveal the frequencies sorted by their total frequencies overall (the default), by the left or right frequency total, or by any individual frequency position. Just press the header of a column to sort it. Press again to toggle the sort between ascending and descending.
You can also get the concordance lines sorted so as to highlight specific collocates, as in the case of the 70 cases of NEVER in R1 position in the screenshot.
