You can create a "virtual corpus" by selecting texts from among the nearly
2,000,000 texts in the corpus. This
allows you to move beyond the categories that we have created (i.e. country)
to select texts from the corpus in any way that you want.
You can use any of the criteria shown to the left to determine what texts
will be in the virtual corpus. All of the criteria are optional -- just use
those that you want.
Note that via this search form, you can only enter one single word in the [WORD] field. If you want to do more complicated searches
with multi-word strings, substrings, lemmas, grammatical constructions, etc then you should create a virtual corpus using keywords. See the
instructions by clicking on TEXTS/VIRTUAL in the search form, and then "Keywords in the Text" (the first link in that help file).
After you've created the corpus, you can add or delete
texts and make other modifications to the corpus. You can also search just within the virtual corpus that you've created;
you can compare the frequency of words and phrases across your different
virtual corpora; and you can generate keyword lists from any of the virtual corpora.
