About Web Concordancer

This program provides basic concordance search and retrieval functions using corpus files which are located on the VLC server. More corpus files will be added in the future, (including Parallel Texts in English / Chinese), so please check for regular updates. You can also do concordances with Associated Words.

Basic Operation

Enter the search string and select from the list box the type of search. This may be:

1. equal to: only exact matches found

2. starts with: all instances containing the search string as a prefix

3. ends with: all instances containing the search string as a suffix

4. contains: all instances containing the search string


The keyword is normally printed but can be gapped if this option is selected. The keyword is then replaced by "(_____)" in each case. Use this option to create classroom concordancing exercises.

Using the % sign

This can represent any letter. Thus for example, a search for equal to b%tt%n will result in concordances being returned for button, bitten, and batten; similarly, a search for %%tten will yield gotten, bitten, cotten and so on, and g%t will find all instances of got and get.


By default concordances will be sorted alphabetically according to the right collocates, but this can be changed to left collocate sort or unsorted by selecting from the "Sort type" list box.


These can be listed separately following the concordance list, listed either alphabetically or by frequency, showing also the number of instances for each collocate. Note that this is only for sorted lists.

Number of concordances

For practical reasons concerning download time and volume it is necessary to limit the number of concordance strings which the search returns. The default is 2000 for sorted strings, and 10,000 for unsorted. You can change this by selecting from the alternatives (500, 1000, 1500) in the "Stop after" list box.

Line width

By default the width of each concordance string is 35 characters to the left and 35 to the right of the key word. Select from the list box options to modify this in the range 30 - 60.

Link to context

The keyword in each concordance string is hyperlinked to the context in which it is found. Click on the keyword to see the wider context displayed.
