The Web may seem like a vast ocean when it comes to finding something you need. Thankfully, search engines can help turn oceans of information into small pools that make finding information easier.

 

This is Web Search Strategies In Plain English.

Before we dive in, let's talk a bit about how search works on the Web. Search engines go out and try to account for every word on every webpage. All this information is then organized for easy reference. When you search for a word, the search engine finds all the pages where the word appears and displays them in the search results. Usually, the pages that appear highest in the search results have lots of other web pages linking to them. Each link acts as a vote to say “this may be a good resource.”

The problem is that there are often too many results. You need a way to reduce the number of results, so you can find what you need. Let's look at how this works.

 

Say you’re looking for a specific kind of fish and these represent all the websites on the Web. Searching for fish doesn't help much. There are way too many results. You need to be more specific. Try to imagine the exact fish and describe it in the search box. You'll see that each word you use gets you closer to what you need.

You can do this for any website by imagining the website that has your answer. What's the title of the page? What words appear on it? If you put those words in the search box, you’ll get closer to finding answers.

But to be a smart searcher, you should know some basic shortcuts. Let's say you’re looking for words that appear together, like a phrase or a quote. An example is a search for information on “sand sharks”. If you search for it like this, the search engine looks for pages with “sand” and “sharks”. To get better results, put quotes around the words like this. It limits the results to the exact phrase.

Here's another shortcut. Words often have multiple meanings. Consider the word “mullet”, which is both a fish and a hairstyle. A search for “mullet” may give you a number of results about the hairstyle but fewer about the fish. To remove the results about hair, place a hyphen or minus sign just before the word you want to exclude, which means “show me the pages about ‘mullet’, but take away results relating to hair.”

 

By being specific and using words and symbols that remove useless information, you can find exactly what you need and keep the Web from swallowing you whole.

 

Words and Expressions:

 

Web: the abbreviation of "World Wide Web"

 

way: as an adv., it means "extremely"

This is Web Search Strategies In Plain English.

The problem is there are often too many results. You need a way to reduce the number of results, so you can find what you need. Let's look at how this works.


Say you’re looking for a specific kind of fish and these represent all the web sites on the web. Searching for fish doesn't help much. There are way too many results. You need to be more specific. Try to imagine the exact fish and describe it in the search box. You'll see that each word you use gets you closer to what you need.

But to be a smart searcher, you should
know
some basic shortcuts. Let's say you are looking for words that appear together, like a phrase or quote. An example is a search for information on “sand sharks”. If you search for it like this, the search engine looks for pages with “sand” and “sharks”. To get better results, put quotes around the words like this. It limits the results to the exact phrase.

Here's another shortcut. Words often have multiple meanings. Consider the word “mullet”, which is both a fish and a hair style.

Before we dive in ,let's talk about something how search words linking on the web.Search Engine go out and try to  find every word on every web page.All the same information is then organized for easy reference.When you search for a word,the search engine finds all the pages  on words which appears in the search results.

Usually,the pages of appears in highest search resultshave have lots of other web pages to them.Each link at the web to say this may be a good resource.The problem is there often too many results.You need to reduce the number of the results ,then you can find what you need.Let's look at how this works.

So you are looking for a special kinds of fish and which represent all the websites on the web.Searching for fish doesn't  help much.There are way too many results.You need to be more specific.Try to meet exact fish and describe in search box,you will see each word you use which is close to what you need.You can do that for any website by imagine every website has your answer.What the title of the page?What was the BLI?If you put those words in the search box,you are close to finding answers.

But to be a smart searcher,you should know some basic shortcuts.Let's say you are looking for some words appear together ,like phase or clause.An example is a search for information on “sand sharks”. .If you search for like this,the search engine looks for pages like sand and shark.To get better result ,put quotes around the words like this.

Use another shortcut. Words often have more meanings.Consider the word “mullet”,which is both of a fish a hair style.A search for mullet,make a numbers of hair style and fewer about fish.To remove all resources about hair,place a hyphen or minus sign just before the word you want to exclude ,which means share me the pages about  mullet ,but take alway with the results of hair.

By being specific and using the symbol that remove unless informationYou can find the exactly what you need and keep the web from swallowing you whole.

The web may seem like a vast ocean when it comes to finding something you need. Thankfully, search engines can help turn  oceans of information into small pools that make finding information easier. This is web search strategies in plain English.

Before we dive in, let's talk a bit about how search works on the web. Search engines go out and try to account for every word on every web page. All this information is then organized for easy reference. When you search for a word, the search engine finds all the pages where the word appears and displays them in the search results. Usually, the pages that appear highest in the search results have lots of other web pages linking to them. Each link accesses a vote to say  this may be a good resource.

The problem is there are often too many results. You need a way to reduce the number of results, so you can find what you need. Let's look at how this works. Say you looking for a specific kind of fish and these represent all the web sites on the web. Searching for fish doesn't help much. There are way too many results. You need to be more specific. Try to imagine the exact fish and describe it in the search box. You'll see that each word you use gets you closer to what you need.

You can do this for any web site by imagining the web site that has your answer. What's the title of the page? What words appear on it? If you put those words in the search box, you’ll get closer to finding answers.

But to be a smart searcher, you should learn some basic shortcuts. Let's say you are looking for words that appear together, like a phrase or quote. An example is a search/ing/ for information on “sand sharks”. If you search for it like this, the search engine looks for pages with “sand” and “sharks”. To get better results, put quotes around the words like this. It limits the results to the exact phrase.

Here's another shortcut. Words often have multiple meanings. Consider the word “mullet” which is both a fish and a hair style. A search for “mullet” may give you a number/s/ of results about the hair style but fewer about the fish. To remove the results about hair, place a hyphen or minus sign/,/ just before the word  you want to exclude, which means show me the pages about “mullet” but take away results relating to hair. By being specific and using words and symbols that remove useless information, you can find exactly what you need and keep the web from swallowing you whole.
