While the live search bars available in boards and topics are useful if you know the general area that you are searching for content, if you want to search for something that you're not exactly sure where it's placed you can use the forum search system by clicking the Search button found in the top menu bar. Once on the search page, look for the "What to search..." area found in the top-left hand corner of the page. In this area you'll see search boxes for the following:
"with at least one of the words" - Type in any word or phrase that you think was used in a post or topic on the forum that you are looking for. The search system will search for all of the words that you use here, but the results you get back may omit one or more words that you have provided in the search box if content is not found for those words. For example, you could type in the quick brown fox in the box provided, and you will receive search results back for any content that contains any of those words. So you could receive a search result back because it has the word fox in it, even if the content does not include any of the other words that you provided in the search.
"with all the words" - In the text area here, type in any words that you are certain was used in the post or topic that you are looking for. The search results you get back will only be for content that includes all of the words you typed into the search box. For example, you could type in the quick brown fox in the box provided, and you will receive search results back for any content that includes all of the words in your search regardless of the order that the words are placed in the posted content.
"with the phrase" - If there is a phrase that you know was used in the topic or post that you are searching for, type it into the box provided here. The search system will look for the words used in the phrase you typed and will return results based on the phrase.
"without the words" - If you have filled out one of the other search boxes in the "What to search..." area of the search page, this box will become available to use. Type in one or more words that you know the content you're searching for does not contain.
Once you have one or more of these search boxes filled out, you can continue on to choose how you want your search results to be viewed as and then click the Search button found at the bottom of the page to get results. Otherwise, you do have the option to use one of the other search filters as well in the other search categories if needed.
