To search word clusters, click Cluster tab on the window.
Search
Enter a word(s)/phrase(s) you want to search in clusters and click Search. You can use wildcard search. See Wildcard Search for more information. The current version has search history from which to choose previously searched words/phrases.
You can set the number of words in the clusters.
These numbers assume your search a single word. So if you search "it is", then 3 word clusters will be actually 4 word clusters (search word(s) + 2 words).
You can also specify the minimum frequency to be displayed on the table. Go to Preferences -> Others and just type any number or use the stepper to change the number.
The result will look like this. The search word(s)/phrase(s) will be colored in red.
You can search different words or cluster with different word length on another table. Or you can change the corpus/database file(s) and then run analysis on the other table. This example has 3-word clusters on the left and 5-word clusters on the right.
Search Span
One of the few options of Cluster is Span. You can set this before your search and search only the clusters that start with the search word(s)/phrase(s) or end with them.
The results will look like these:
Left Only
Right Only
