Indexing and searching XML with swish-e

If you have Lynx, a text-based browser, then you should be able to run Lynx and point it to one of the files in the results like this: lynx xml-data/xhtml/marc2xhtml/honda-how-1071929753.html . Altern- atively you could open any of the files in your graphical browser.

Swish-e supports a bevy of search operations including all the expected Boolean operations, phrase searching, field searching, right-hand truncation (implemented using a "*"), and nested queries. Con- sequently, all of the following swish-e queries are valid:

  • swish-e -f swish-indexes/xhtml.idx -w origami

  • swish-e -f swish-indexes/xhtml.idx -w origami and colorful

  • swish-e -f swish-indexes/xhtml.idx -w "colorful origami"

  • swish-e -f swish-indexes/xhtml.idx -w title=origami

  • swish-e -f swish-indexes/xhtml.idx -w author=honda

Using the -p command line option you can alter the output to include the properties denoted in your con- figuration file. Thus the following command, swish-e -f swish-indexes/xhtml.idx -w author=honda -p pagination , will display the pagination as well as the default information (again, lines have been hard- wrapped for readability):

$ # # # # # #

swish-e -f swish-indexes/xhtml.idx -w author=honda -p pagination SWISH format: 2.4.2 Search words: author=honda Removed stopwords: Number of hits: 2 Search time: 0.001 seconds Run time: 0.045 seconds

Indexing other XML formats

Indexing and searching other XML formats is very similar to indexing XHTML. First you create your content. Then you write a swish-e configuration file. Third, you index content. Fourth, you search. Last, you retrieve while optionally transforming your XML for display.

Let's index a set of MODS files. Open any of the MODS files in the xml-data/mods/many directory. Take note of the element names. Open swish-indexes/mods.cfg and take note of the MetaNames and PropertyNames directives. Notice how swishtitle has been added to the MetaNames directive. Swishtitle is a meta data value you get for free with swish-e, but in order for it to be searchable in your index you sometimes need to specifically include it in the configuration file. Index the MODS data with the com- mand swish-e -c swish-indexes/mods.cfg , and give the following searches a whirl:

  • swish-e -f swish-indexes/mods.idx -w title=cannery

  • swish-e -f swish-indexes/mods.idx -w love -p title
