Instructions

Combining results from multiple search engines

Sometimes it is particularly important to get lists of URLs matching a search that are as exhaustive as possible. This can be achieved in LexiURL Searcher by running the same searches in Yahoo and Live Search (excluding link searches, which do not run in Live Search) and then combining the results. Although it does not make sense to combine the short results files, the URL lists in the long results files can be merged by using the Merge two long results files with overlapping or identical queries option in the Utilities menu and then selecting each of the files to be included. The resulting merged file has duplicate URLs eliminated and can be used as input for any LexiURL Searcher facility that processes the long results files. For example, when preparing a web impact report, the results of different search engines could be combined before selecting the Make a set of Standard Impact Reports option from the Reports menu in order to generate a more comprehensive report.

Creating network diagrams interactively

Network diagrams can be built site-by-site or page-by-page in SocSciBot Network, using its inbuilt menu and right-click menu options to download pages and add to the diagram the pages that they link to. For example, start SocSciBot Network from LexiURL Searcher’s Show SocSciBot Network menu option in the File menu and start by deleting the default diagram by selecting Delete the Whole Network from the Edit menu. Now add a first page by selecting Add New Node from the Edit menu and entering the domain name cybermetrics.wlv.ac.uk as the node name. To add web pages linked to this one, select the new circle by dragging the mouse over it, and select Crawl (recursively download) from selected node(s) and add all links to diagram from the right-click menu. Enter the crawl depth 1 (just follow links from the page), leave the search text blank and wait for it to crawl and update the diagram. See the online documentation for SocSciBot Network for more information.

Processing longer lists of searches

If more searches than the maximum daily total need to be processed then LexiURL Searcher will stop just before the limit and produce a dialog box asking what to do. The easiest option is to wait 24 hours before clicking on the option and then increasing the search limit in the new dialog box by 4,500 (Yahoo) or 9,500 (Live Search), allowing the searches to continue. The 24 hour delay is necessary to obtain a new API limit “allowance” from the search engine and it is a good idea to set the limit at a few hundred less than the daily maximum to be on the safe side of the limit.

Gaining over 1,000 results per search

If there are more than 1,000 results for a search then this is a problem due to the search engine 1,000 result URLs maximum. In the professional version of LexiURL Searcher it is possible to gain extra matches using the “query splitting” technique. This option is not available in the free version because it generates many additional searches, so makes extra demands on the search engine used. Please email the author if you are a researcher and need this extra capability.
