FULLTEXT AND ATTRIBUTE SEARCH

Hyperwave Information Server lets you search the content of text documents in most common formats, such as Microsoft Word, Microsoft Excel, HTML, RTF, and Lotus 1-2-3. This option is a powerful aid in getting the information you need. For example, you may be working for a big company with a large server that contains information that is useful to you on the job. You can think of this large information repository as being analogous to a library. As in any library, you can search by document title, but with Hyperwave Information Server you can also search on content. This is like being able to search every page in every book in a library for a word or combination of words in a single step. The default server interface allows you to search in fulltext, as well as by certain attributes. These attributes include Author (the name of the person who uploaded the object), Name (the URL of the object), and TimeModified (the date and time a document was last modified). Searching by date of last modification allows you to limit your search to find only the most up-to-date documents.

2.2.1.1 The Verity Search Engine

• a thesaurus, to find documents that contain words that have the same meaning as your search term
• a function that finds grammatical variations of the search term (for example, if you enter the term "compute" you will also find any documents that contain the words "computing" or "computers")
• a function that finds words that sound like your search term
• case-sensitive search
• a function for associating one or more search terms, e.g. all search terms should be found in the same document, same paragraph, same sentence, etc.

SIMPLE SEARCH WITH VERITY

To use the simple search form with Verity, do the following:

1. Click on Search on the toolbar.
2. In the dialog box that appears (see Figure 14), enter a search term or terms in the Search For text box. Multiple terms are combined with "OR"; i.e. at least one of the terms is present in every document found.
3. Select what you want to search in under in Document. You can search on the attributes of objects or the content of text documents. At least one of the checkboxes must be checked. See page 139 for a list of attribute types with explanations.
4. Select the search scope using the in Scope list box. This tells Hyperwave Information Server which part of the server it should search on. You have the choice between searching the collection you were browsing when you accessed the search form or searching the entire server.

Your system administrator may add further scope options.

1. Click on the OK button.

The extended search form offers additional options for finding documents by searching by document owner, creation date, or date of last modification. Also, the results of the search can be filtered by MIME type and language. Of course the extended search form lets you take advantage of all of Verity's advanced features. Extended search with Verity is done as follows:

1. Click on Search in the toolbar. The Search dialog box appears. Click on the Extended Search button in this dialog box.
2. Enter one or more words in the Search For text box.
3. Switch content search on or off by selecting or deselecting the In Contents check box. When content search is turned on, the thesaurus, variations, sounds like and case-sensitive checkboxes can also be selected. Use the listbox to specify how you want the search terms to be associated in the documents found, e.g. all words in same document (AND), all words in same sentence, etc.

1. Select any or all of the attribute types (Title, Keyword, etc.) you want to search in using the checkboxes. Use the listbox to specify whether you want all (AND) or at least one (OR) of your search terms to be present in the attributes of the objects found.
2. Optionally enter a Hyperwave Information Server user name in the Owner text box if you want to find objects created by a particular user.
3. Enter preferences for date created and date modified of the objects found. The date can be entered in the form MM/DD/YYYY, e.g. "03/30/98" or relatively to the current date. A relative date can be specified in terms of minutes, hours or days. You can, for example, enter "-3days" or "-3d" to mean "the date which is three days before today". By entering "-3d" in the "after" text box of the search form, you can easily find all documents which were uploaded to the server in the last three days. It is also possible to enter e.g., "-2minutes" to find documents inserted in the last two minutes, or "-1hour" to find documents inserted in the last hour.
4. Select a MIME type from the listbox if you want only a particular document type in your search results.
5. Select the search language. Default choices are German and English.
6. If you don't want the documents found to contain a particular word, enter the word in the appropriate text box.
7. Select the search scope using the in Scope list box. This tells Hyperwave Information Server which part of the server it should search on. You have the choice between searching the collection you were browsing when you accessed the search form or searching the entire server.

Your system administrator may add further scope options.

1. Click on the OK button.

2.2.1.2 The Native Search Engine

SIMPLE SEARCH WITH THE NATIVE SEARCH ENGINE

Simple search is the same whether using the Verity or the native search engine. See page 34.

The extended search form offers all the search functionality of the simple search form and more. Here you can additionally search by author, language, time created, time modified, etc. It is used as follows:

1. Click on Search in the toolbar. The Search dialog box appears. Click on the Extended Search button in this dialog box.
2. In the Extended Search dialog box that appears (Figure 16), enter one or more words in the Search For text box.
3. Turn content search on or off by selecting or deselecting the Full Text Search button. Use the listbox to specify whether you want all (AND) or at least one (OR) of your search terms to be present in the content of the objects found.
4. Select any or all of the attribute types (Title, Keyword) you want to search in using the checkboxes. Use the listbox to specify whether you want all (AND) or at least one (OR) of your search terms to be present in the attributes of the objects found.
5. Optionally enter a Hyperwave Information Server user name in the Owner text box if you want to find objects created by a particular user.
6. Enter preferences for date created and date modified of the objects found. The date can be entered in the form YY/MM/DD, e.g. "98/03/30" or relatively to the current date. A relative date can be specified in terms of minutes, hours or days. You can, for example, enter "-3days" or "-3d" to mean "the date which is three days before today". By entering "-3d" in the "after" text box of the search form, you can easily find all documents which were uploaded to the server in the last three days. It is also possible to enter e.g., "-2minutes" to find documents inserted in the last two minutes, or "-1hour" to find documents inserted in the last hour.
7. Select a MIME type from the listbox if you want only a particular document type in your search results.
8. Select the search language. Default choices are German and English.
9. If you don't want the documents found to contain a particular word, enter the word in the appropriate text box.
10. Select the search scope. This tells Hyperwave Information Server which part of the server it should search on. You have the choice between searching the collection you were browsing when you accessed the search form, searching the entire server, or searching the server pool if the server is a member of one.
11. Click on the OK button.

2.2.1.3 Refining Queries and Creating Query Objects

After you have run a search, you can click on the Refine Query button at the bottom of the search results page to change the query you entered for that search and run a new search.

QUERY OBJECTS

Hyperwave Information Server also allows you to create query objects, which are queries that are stored on the server in the form of a collection. Query Objects are created by clicking on the Save Query button at the bottom of the Search Results dialog box. Users can activate the query object whenever they choose, and its results are displayed in the collection. The Query Object feature can only be activated by identified users in Authoring mode, and is described on page 45.
