Search help
Simple search
You input the word(s) you want to search for. The best hits are presented
first in the list you get. If you input trafik as one of your
keywords, the search engine will find documents which contain the following
words: trafiksignal and trafikering, but also vägtrafik or biltrafik. If
you do not want to use this function, you can put a mark in the field "no
truncation" (see below). You cannot, as yet, search for a phrase. The
documents you find after having searched for e.g. ökad
säkerhet(increased safety) need not therefore contain just these two
words together.
Upper and lower case
The search engine is case sensitive. A search for räls(rail) will
therefore probably produce more hits than a search for Räls. A
search for rÄls will probably result in 0 hits. For more information
on this subject see below - "case sensitive".
Truncating
Truncation replaces the beginning and/or end of a word. In Full Text
search the words you are searching for are automatically truncated.
"Without automatic truncation"
If you put a mark in the field "without automatic truncation", the search will
be performed for exactly the way you have input the word(s).
Simultaneous search for truncated and non-truncated words
By using quotation marks "" you can simultaneously search for
truncated and non-truncated words. The search säkerhet "bil"(safety
"car") will produce hits for trafiksäkerhet, säkerhetens etc,
with "bil" without a prefix or ending.
"All words must be searched"
If you put a mark in the field "all words must be searched",
only those reports that contain all the words you have input will be
presented. Otherwise, what usually happens is that when you are searching
with several words, the search is performed for documents where one or more
of these words occur. Naturally, when the results are presented, the
documents which contain all keywords will appear before those which contain
only one of the words.
"Case sensitive"
The search engine is case sensitive. However, when a search on
"its" finds documents containing that word in upper or lower case
or a mix thereof, a search using "ITS" will only find documents
with that word in upper case.
A mark in the box "case sensitive" will force a search on
"its" to retrieve reports where that word in lower case
occur.
Advanced search
You can get better hits by using the symbols + (plus) and – (minus).
Plus is used to indicate that a certain word must appear on a page. Minus is
used to exclude a certain word.
If you are searching for +transport –container, you will get
hits where transport appears on a page while container does not appear at
all.
"Hide summaries"
A mark in the box "hide summaries" before the search will show
only the URL:s of your hits.
Stop words
Several search engines do not record extremely common words or combinations
of two letters in order to save space or to speed up searches. These words
and combination are known as "stop words." The database "Full text
search" at Transguide does not index these stop words. A search on
"TV" (with the option "without automatic truncation" )
will result in no hits.
More about the contents of
Full text search
The database comprises about 15 000 reports, articles and conference papers. This number is increasing as more and more people are
placing the results of their research on the Internet.
By far the greatest proportion of the material comes from Swedish
universities, authorities and other organisations. Work on collecting links
to full text documents commenced in the autumn of 2000. Most of these are in
pdf format. A web search engine scrutinise the documents word by
word and compile the database on the basis of this. The results of your
search are presented by title and description, taken from the pdf file or
the web page. Naturally, there is also a link that you can click to access
the report itself.
In contrast to the database "Electronic documents"
which is a library catalogue of electronic documents, in Full Text search
you are searching the full text of the documents. The combination of searching all of the text together with the
advanced selection of documents make "Full text search" at Transguide a powerful work tool.

The reference begins with the title of the web page or the pdf document. The title is thus determined by the person who has produced the
document. If no title is found the web address is shown.
Description can consist of the initial lines on the web page or in the
pdf document. It can also be fetched from the contents in a "meta-tag".
In both cases it is thus a matter of a text produced by the author of the
report or by the person who has put the document on the Internet.
Document information consists of the size of the file the link leads to.
This information may be useful to know when one wants to download the
document. The date (and time) when the document was put on the Internet or
when it was most recently modified is also given. If such information is not
available, the date when the search engine most recently indexed the
document is given here instead.
The item is terminated with the full address
(URL) of the document.
Updating
Full text search is updated when new or modified information is available.
