Both the dynamically created screens and the searching capabilities
were implemented through CGI scripts written in Perl on the UNIX server.
The user could browse through collections by period looking at thumbnail
images, which then had links to the full data records. They could also
do fielded searches or simple searches by all fields for a specified
keyword. The available Boolean operators were "and", "or", and "not".
The options for display of the results were a mid-size image of the
artwork, the type of object, the credit line and label data fields.
The user could click on an image to get larger sizes.
index was created by Glimpse, a search engine package. Their system
allowed for full-text searching of object descriptions only. The types
of searching available were Boolean, fuzzy match and case sensitivity
in all fields. The display of a search result was text with the museum
name and object title/caption highlighted. The skills primarily needed
were database development, and knowledge of C, Perl and shell scripts.
In Year 2 a programmer/Web specialist was added to the staff.
used the search engine built into FileMaker Pro. The database was accessed
from the Web using ROFM CGI shareware. Both fielded searches and generic
keyword searching were supported. Only the Boolean operator "and" was
supported. Other features included searching by date range and exact
match, and links to definitions of the MESL data dictionary terms. The
display options for search results were either a thumbnail image with
brief text or text only. The user could modify both the number of records
and/or images displayed, and sort the result set.
implemented a search engine that used a web-based form interface to
query an SQL-server database through CGI-scripts written in C++. Fielded
searches were not offered. The search interface was a single line for
input. The entered terms were searched for in each of the indexed fields
(when multiple words were entered, a default Boolean "and" was inserted).
There were two options for displaying search results: non-frame and
frame. The non-frame version displayed up to 10 thumbnails and brief
indexed record; the user could click on the image and retrieve a medium-size
version. The user was also able to retrieve all 32 MESL dictionary fields.
The frame version allowed for the same display as the non-frame display,
but when the user clicked to retrieve the medium-size image the image
was displayed in the same browser screen, but in a different frame.
The medium-size images and up to 10 thumbnails can be displayed simultaneously.
provided browsing capabilities in both their web-based and their SearchSlide™
implementations. Their web-based implementation allowed for searches
by artist, title and keyword and it was case sensitive. The SearchSlide™
implementation allowed for very complex Boolean searches. The simple
query function was a Boolean "and" of all search fields selected. There
were two search results display options, one was to view a thumbnail
and its accompanying text, and the other was to display the results
as a screen of thumbnails. An additional functionality that they were
able to make available through SearchSlide was the ability to
create an "electronic carousels" of images; that is, to create a left-screen/right-screen
list of objects. These images could then be saved and projected in the
classroom side by side via ProjectSlide.
used a custom-developed search engine, Full Text Lexicographer, which
offered many complex search features such as: Boolean "and", "or", "not"
and "and-not" searches, proximity searching, fielded searches, automatic
stemming, and searches by numeric ranges. Full Text Lexicographer offered
incremental updates and deletions, and it was usable from the command
line or as a back end to other programs. The search results were sortable
by any searchable field, and display options included thumbnail view
or text list, and all structured data viewable for all records. In addition,
they provided a table of searchable terms and phrases and a table of
special character substitutions.
They used Open Text technology, a sophisticated high-speed searching
tool, for indexing, searching and retrieval. Perl scripts were written
to generate the web pages on the fly. Their search interface offered
fielded searches. After completing a search, the user was presented
with an intermediate screen which listed the number of results. The
user could choose from three types of displays: thumbnail with brief
record (linked to medium sized image and full record), thumbnail with
checkbox (user checks images for subsequent display of the brief record),
and brief record only (the user then selects records to see thumbnail
