Searching Hints & Tips
How do Search Engines Actually
Work?
Search engines use software to spider the Web and create their databases.
These are also sometimes called robots, web crawlers, or worms. Web
pages are retrieved and indexed by these
search
engines.
When you
enter a query at a search engine, your input is checked against the search
engine's keyword indices. The best matches are then returned to
you as matches.
No1: No search engine covers very much of the vast material available on the Internet! Imagine millions and millions of documents & files of various kinds.
Ingen sökmotor täcker särskilt mycket av det otroligt omfattande materialet som finns på Internet! Tänk dig att det finns miljontals och åter miljontals dokument & filer av olika slag.
Vissa sökmotorer är bra till vissa saker, andra till annat. Om du vet att materialet du söker är skrivet och publicerat (digitalt) i Sverige, ja, då kan du ju söka här hemma med hjälp av en svensk sökmotor/sökmotorversion som www.yahoo.se eller www.google.se.
Söker du material som
du tror finns utomlands och/eller är publicerat på ett annat språk än
svenska, ja, då skall du naturligtvis söka med ett annat språk än svenska
och du skall definitivt inte besvära dig med att använda svenska sökmotorer/sökmotorversioner.
Se
språkval samt ev. landskod, URL:en slutar med .se,
mm mm!
Flera
kriterier finns som hjälper dig fastställa en sidas hemvist.
Kom också ihåg att olika motorer fungerar mer eller mindre bra med hjälp av varierad sökteknik som att använda citattecken/citationstecken (" "), plustecken ( + + ), minustecken (- -) eller asterisk/"stjärna" ( * ). "Stjärnan" i dagligt tal, egentligen benämnd 'asterisk' är ju något av en joker i leken och kan med framgång ibland användas då man är osäker på exakt stavning eller variant av ord, eller exakt frasinnehåll.
"
" citattecken använder du när du
skall ha tag på ett exakt uttryck eller ett givet namn där sökobjektet/sökmålet
innehåller flera ord. Här är oftast citattecken ett bra och väl fungerande
grepp.
I'd like to find me a "yacht of more than 30 feet"
* * asterisk/"stjärna" klan* fångar kanske både 'klant', 'klang' & 'Klangehamn' så använd asterisk med förstånd & skärpa
+ + plustecken +saltgurka +falukorv fångar med automatik de sidor som innehåller exakt orden 'saltgurka' & 'falukorv' och i den formen
- - minustecken -kalle +Sigrid eliminerar automatiskt sidorna där det står om järngänget 'Sigrid' & 'Kalle' & 'Halta Lotta' och gallrar så att säga fram med finess & bravur endast de intressanta sidorna som du vill ha där endast Sigrid beskrivs eller omtalas.
...och, som sagt var, eftersom ingen sökmotor eller sökteknik fungerar över hela fältet så är det viktigt att känna till några av förutsättningarna och de här ovan nämnda klarar man sig icke utan. Resten är fotarbete, fotarbete och tid & tålamod i kombination med fantasi & envishet. Naturligtvis underlättar ett visst språkligt intresse för detaljer.
SEARCH
- For those not used to search and search functions within the computing
environment, searching on the Internet & searching in a database sometimes
need an x-tra amount of consideration & thought before getting started.
Learn about 'wildcards' & 'wildcard characters'
before you find yourself in a very time-consuming situation, confused, out of
time, lagging behind, not knowing anything or little at the most,
sometimes with
a feeling or sense of realization
that there is really no information to
be found.
'Wild
card' is a method permitting an operating system to perform utility
functions on multiple files
with related names without the user or programmer
having to specify each file by its full & unique name.
That's why you
sometimes might end up
finding "Donna", "Dona",
"Donald" and "Don"
when you've searched for "Don".
Remember
also to get your 'slash' right (/)...
When
you're in system folders and directories you want a (your) slash tilted to the
left ( \ )
whereas when you're on the Internet or on your local Intranet you
want to use "the right one" (/).
Quite
frequently colleagues turn to me complaining about the lack of information.
Now
there's usually never a single digit right in that assumption.
Good
searching needs common sense,
creativity, technique and an
on-line computer.
-That's about it!
Technique
can be acquired by reading thoroughly through the instructions found at major
search sites.
Also,
there's usually very good information to be found in your own
Web Browser under
Help.
MS
Internet Explorer
Help has this to say: "As you search for items on the
Internet,
you may want to
customize the way you search.
You can choose which
search categories are available and which search providers to use for your
searches."
Also,
of course, it is important to become aware of the importance of "the
plus" (+).
If you want to find something consisting of two words
where the word order doesn't matter
you type a plus (+) before each word (+bilar
+Chevrolet).
If you want pages or websites containing information in Swedish
about Chevrolet cars, this is it.
If the word order is significant (important)
you use a quotation mark at each end (before the first word and after the second
word). This way you make sure you end up finding pages where these words are
found exactly the way you wanted them.
Type mainly using small letters unless
otherwise required by circumstances,
because 'peanut' will find 'Peanut' but
never will Peanut find peanut (groundnut)!
Learn
somewhat here
about
'wildcards' & wildcard characters...
NOW!
Here are some wildcard characters & their meanings
? any single character in this position
* any number of characters in this position
# a single number in this position
[] find these characters
[!] don't find these characters [!character here]
If
you make a habit of using these characters in your search activities you
can rest assured regarding utilizing your limited time and
making the best of it.
Example
If you were to search for h?ll you would
find
hall, hell,
hill, hull, håll, häll, höll but you wouldn't find 'hålla',
'hälla' etc. which would require the following
search text: h?ll?
Similarly you would find 'the', 'true', 'tongue' but not 'tea' if you were to search for t*e
-Please
be aware of the fact that some sites, pages & databases do not accept
or even work with characters other than letters and numbers!
This, among other
things, is what makes it so darn important to be creative and search
in various ways and manners
using different
techniques as part of your regular search behaviour.
Don't
forget WHAT language you're using,
and remember that sometimes it might prove
quite efficient even trying out words & phrases (in another language!)
which you actually have to
look up first on your own.
Don't
depend on one language only when searching!
Make a habit of
looking
up words you don't understand!
