The point of it
You might want to process only the speech of elderly men, or only advertising material, or only classroom dialogues. This function allows WordSmith to search through each text, e.g. in text headers, ensuring that you get the right text files and skip any irrelevant ones.
Suppose you have a large collection of texts (e.g. the British National Corpus) and you cannot remember which of them contain English spoken by elderly men.
Knowing that the BNC uses stext> for spoken texts, sex=m for males, age=5 for speakers aged 60 or more, you can get WordSmith to filter your text selection. It will search through the whole of every text file (not just the tags or header sections, in fact the first 2 megabytes of the file) to check that it meets your requirements.
You can specify up to 12 tags, each up to 80 characters in length. They will be case sensitive (i.e. you will get nothing if you type Age=5 by mistake).
Horizontally, the options represent combinations linked by "or". Vertically, the combinations are "and" links. The bottom set represents "but not" combinations.
You only want text files containing both the word cats and the word dogs: type cats into the first box, and dogs below it.
You want either roses or violets, and flowers must be present too: write roses and violets into the first two boxes, beside each other. Write flowers in the leftmost box on the next row down.
You want book or hotel but only if they're not in a text file containing publish or Booker Prize: write book into the first box, hotel in the box beside it, and publish* and Booker * in the first two boxes in the bottom row.
