TexNet32 - Database indexes

You can use the "Index..." option in the "File" menu to create and access keyword indexes to various files, whether these contain source texts, abstracts, or other material that you want to be able to search.

When you first use the "Index..." option, you will be prompted for an index file. You can select an existing *.tni file, or you can create a new one by typing in the new name. TexNet32 will then display the "Database index" form:

When the "Database index" form is first displayed, the *.rtf pathname of the file that you were working on in the currently focused window in Texnet32 will appear in the list of pathnames below the "Search" button, even if you have not yet saved the file in *.rtf format.

Use the "Open index" button if you wish to select or create a different index.

You can use the "Pack index" button to restructure the index so that it takes up less space and can be searched more efficiently. When the packing is complete, a display of before-and-after statistics will appear. Click on the display's "Close" button to hide it.

When you have an index open, a list of words in the index will appear in the list box in the upper right section of the form. To move quickly to a specific part of the word list, click on the "Find word" button.

To search for indexed files containing specific combinations of keywords or stems, enter a query in the Boolean query edit box and then click on the "Search" button below. The question mark ("?") can be used as the sign of right truncation. You can use the buttons to the right, next to the list of words in the index, to copy words from the index, Boolean operators, or parentheses into the edit box. When a search is complete, an updated list of file pathnames will appear in the list box below the "Search" button.

If you want to see a list of all the files that have been indexed, click on the "All" button.

If you want the list to show the pathname for an existing file that you select, whether it has been indexed yet or not, click on the "Browse" button. This is especially useful for indexing files that you do not want to load into a main TexNet32 window.

To view the contents of a file, select its pathname in the list and then click on the "View" button. If the file is available, its contents will be displayed in the RichText edit box below: *.rtf and *.txt files will appear appropriately formatted; other kinds of files, including TexNetF *.doc and *.net files can also be viewed, though no special formatting will be applied.

You can copy selected text in the file RichEdit box to the clipboard or search for particular character strings in it. To access these options, right click on the RichEdit box.

If you want words and stems from your query to appear in bold in the file display, check the "Highlight query terms" checkbox before you click the "View" button. Note that this option has the effect of cancelling other typographical variations when the file text is displayed.

To add a file to the currently open index, first make sure its pathname has been selected in the list and then click on the "Index" button.

To remove a file from the currently open index, first make sure its pathname has been selected in the list and then click on the "Deindex" button.
