First, I want to say that I don't mind taking the time to find things on the site for other people. It makes me feel useful and doesn't cost me more than time. That said, I suspect many people aren't fully comfortable with all the functions on the Permies search feature. I don't know how many people don't find what they're looking for and give up without asking questions about it. So I hope no one finds it arrogant that I'm going to try to walk people through how use this feature. I even looked up how to post a screen shot to make this multi media
I'm not a natural teacher, but I'm going to try to make this helpful.
When I was looking to see if there was information on clematis, I could use that word. Armed with that word I was able to scan the results for the whole site and see that there was little more than lists using that word. I clicked into the few threads that had repeated use of the word and confirmed that they weren't what I was looking for. This was fast and easy because there wasn't much information to filter through.
For a very popular subject like
water harvesting you wouldn't want to just use the term water, any
thread that uses that term would be in your results leading to dozens of pages and most of those threads would have repeated uses of the word. You could narrow your search down by making sure you've selected match exact phrase. That's a huge number of results still. If you're not starting from the very beginning, maybe you have a particular type of water harvesting you want to know about. Or maybe you are a beginner and you want to know where to start. Maybe the term you use has a synonym which some one else used when giving detailed information, maybe it's a step by step discussion of how to do something but no one used the word 'start' or 'beginner.' If you used an exact phrase, maybe they just put the words together in a different order. The more words you add the more easily you'll weed out relevant threads accidentally.
This is when you start moving on to other parts of the search feature. Some of you may be looking for a particular thread and remember part of the name. You could use the search subject only. I think that's pretty straightforward, but I've never used it, so moving on...
You can select which part of the forums to search from the pull down menu. The very first option is "all available" I use this option whenever possible because so many
permaculture techniques stack functions that make them appropriate in multiple forums. For our example phrase "water harvesting" I just counted twenty-one different forums in which a discussion of the topic would legitimately be found, without going off topic in another discussion. This is where you need to start narrowing down by your reasons for needing the information. If you are planting a forest garden and you want to know how to catch water for
trees, then select 'forest garden.' If you're developing a farm, select from one of the farming forums (or search each one individually) Try to work from the most relevant to the least relevant.
Now, I'm assuming you have a list of results. There's still tricks even here. Obviously there's the nice bit where the search results will show you the found phrase or sentence containing your search term. I like to group my search results by topic. If you below each result grouped that way, any other times those words came up in the same discussion are then shown highlighted in yellow at the bottom of the result. Between the displayed sentence and the amount of posts using those words it is usually easy to find where people where discussing a subject in more depth. Weed through the few results which have the greatest amount of discussion at this point and you'll probably find relevant information.
