Advanced search operators

Introduction

`Advanced search operators Examples of an advanced search This is my first search, not advanced this shows me searching for EMA, the first thing I can see is the amount of websites is much more than I would have thought, as EMA is only one company and only for one thing (to pay 16-19 year olds for been in education) I would have excepted less than 19,000,000 searches but what I can see is it is not on 'pages only in uk' this then reduces my search by nearly 15 million. Just EMA + East Riding came up with a lot more, than I except, as East Riding is not that big of a region. And it shocked me that the search came up with 30,400 searches so that is still to many I need to narrow my search more! I then decided to narrow my search and search for EMA in East Yorkshire not in hull. So my search looked like this and I found that my search went down from 1,540,000 to 30,400 then searching for not Hull I narrowed my search down to 6,000, and that was searching the web, not 'pages from the UK' this came up with a much smaller amount of only 678! ...read more.

Middle

Straight away, I can minimize the amount of sites buy specifying to in the UK my sites to choose from dramatically de-crease to 58,800,000. So first of all I will start by searching for weather, then I want to narrow my search down so I will now search for weather + today, something that I didn't expect was for my first weather + today search to come up with in UK websites was BBC, world weather, then bellow that was, BBC weather centre, UK which is more appropriate and what I wanted, I had specifically asked for uk sites hoping that uk weather would come up. Overall for my second search this is good. Over I million searches is a lot and it is not accurate or precise, so I think I will need to specify my search again to see what happens, I predict putting 'weather + forecast + today' and see what happens, on yahoo there was only a small reduction from 1.7 million to 1.4 million so even though that is 30,0000 decrease out of nearly 2 million it is not that much of a decrease in WebPages. So now I will specify were about in the UK my search is going to be, because i live in the Humber I will now type 'weather + forecast + today + Humber' this search has now been dramatically lowered from over 1 million to 23,000 that was very effective. ...read more.

Conclusion

My 1st search on yahoo came up with the BBC weather channel which is much more appropriate and I was surprised at this, I thought it would be much better search ion Google, and when you specify your search it does come out well but still there is less efficient web sites with Google than yahoo, and the amount of websites it finds it much more (200) I was surprised to find this. Google search for weather Yahoo search for weather Conclusion, My final search which was weather + forecast + today + Humber. BBC, was of a much better search on yahoo. I generally found more 'bad' websites on Google than yahoo, this was un like my prediction because, I usually use Google as I thought Google was a better search engine but my results say differently. Advanced searches are more professional and quicker ways to search for things yet just narrowing down your search is also a good way to search. Many things made think Google would be a better search because, it looks clearer it looks easier to use. I have now shown it is easier and is clearer to use, especially as I have shown the advanced search is very easy to find on Google, but I have been proved wrong as the good searched and more accurate searched tended to be on Yahoo not Google. ?? ?? ?? ??
