Here's a screen-shot of the web version.
This is a screenshot of the older version that runs under Windows locally.
A fraction of a second for 'exact' and 'starts-with' matches across the entire corpus of Old English, even when the search includes variant spellings, and two to three seconds for 'ends-with' or 'contains' searches. Three or four seconds for phrase searches and proximity searches.
These are typical times for the 500mhz Pentium which is several years old; currently shipping Pentium PCs are almost six times faster and search results will be virtually instantaneous.
To find words with any of the special characters (æ, þ, and ð) just right-click on the mouse and a popup menu will appear from which you select the character you need. But if you prefer to type, use &ae; for æ, &t; for þ, and &d; for ð, &e; for tailed e (ę) and &lbar; for the barred L.

To limit a search to Prose, Verse, or Gloss, just click the appropriate checkbox. To select the type of comparison for the search ('equals', 'starts with', 'ends with', or 'contains') choose the appropriate comparison operator from the dropdown list. The search term may contain one or more individual wildcard characters (e.g. starts with y?de) no matter what type of comparison is chosen.

You can search Prose only, Verse only, or Glosses only, or any combination of the three.

You can limit the display of text-contexts to a particular title or titles. Simply place a check next to the title(s) in the pane where the hit counts are displayed (see the screen shot below).

TRSearch provides a very easy way to search for a word using variant spellings. Simply check the "Meta" checkbox to turn variant-search feature on. Then, when you enter a word, e.g. "swustor", a list is displayed. You can use any or all of the words in the search. You can quickly select all of the variant spellings with a single click, or select/deselect individual variants. (Sometimes the search results will include spellings that match the pattern but which are not variant spellings of the word you have in mind. These are easily excluded from the search by a single click on the checkbox next to the word, which turns it "off" so to speak.) You don't have to search spelling-by-spelling.
  • MetaSearch treats -þ- and -ð- as if the same letter.
  • The letters -c- and -k- and -g- (when -g- is in final position) are treated as if the same letter.
  • The letter -g- before the front vowels -i- and -e- is treated as a vowel. (e.g. wineard = wingeard ).
  • Single vowels and vowel clusters are treated as 'vowel'.
Since the variants feature can also be used in conjunction with the operators ('equals', 'starts with', 'ends with', and 'contains'), it offers results that are comparable to those obtained with "regular expressions" while being much easier to use, requiring no knowledge of arcane regular expression syntax.
TRSearch offers a proximity and phrase searching feature. When you select Proximity Search from the menu, the screen changes to accept two words:
Between the words is a number widget that accepts the distance value for the proximity. A distance of "1" is used to indicate that the words must be adjacent, with no words separating them. You could do a phrase search in this way if you wanted to find the phrase without concern for the order of the words in the phrase (e.g. "sette wingeard" or "wingeard sette"). Use greater distances to expand the context. To find a phrase matching the words in the order you have provided them, select the Phrase option from the Search menu.

The TRSearch proximity-search algorithm is very efficient and this type of search is also very fast ... just three or four seconds.

The Proximity and Phrase searches incorporate the variant spellings Meta search feature, as well as the standard operators (equals, starts with, contains, ends with) so you are not confined to one spelling even in this type of search. You can use the variants search feature to gather alternate spellings on one, both, or neither of the words involved in the proximity search.
Legal Requirements
So as not to infringe upon any copyright, TRSearch desktop versions ship with no content whatsoever from the Old English Corpus which is under copyright of the Dictionary of Old English Project at the University of Toronto. To use one of the desktop versions, or to activate an account to use the web version, you must first obtain an individual license to use the Old English corpus files. Copies of the Old English corpus were available through the Oxford Text Archive free-of-charge if they were downloaded over the Internet though one had to complete a hard-copy license application form and send it to the OTA. Corpus files in SGML and HTML formats for individual use are available from the Dictionary of Old English Project at the University of Toronto for a fee of $200.
TRSearch is available in three versions, a desktop version using Microsoft .NET for Windows, another using Adobe AIR for Macintosh OSX or Windows, and an online web version (HTML + javascript + CSS) that runs on most browsers (IE, Firefox, Chrome, Opera, Safari, Mobile-Safari, Android browser) and communicates with a web-service.
As you may know, developing software is not inexpensive: developers can incur significant out-of-pocket costs in setting up a development platform (hardware and software development tools). For these reasons, TRSearch will not be licensed as freeware, but the two-tiered (student/retiree discount) license fee is comparable to a modestly priced hardcover book from an academic press.
