Google recently introduced a change on search that moved the search options and filters from the left side to the top of the page. Search filters include selecting one of Google's specialized search engines instead of Web search, for instance shopping, images or maps, selecting a time results need to have been published in, or related options like verbatim search or only pages that have not been visited yet.
The change moved the sidebar options to the top of the results, but not all of them are visible immediately. Only the option to switch to a specialized search engine remains the same, while all other search filters are hidden under a search tools button.
You need to press that button to display the any time and all results options to filter results by time or other factors. The main problem here is that the change does not stick. When you leave the search results page for any reason, it gets restored to the default next time you open it. That's problematic for users that often work with the search tools Google makes available.
If you dislike the position change on Google Search, you may be interested in a userstyle that is available that restores the old search options position on Google's search engine.
Google Search options/filters to the left is a userstyle that you can install in browsers such as Firefox, Google Chrome or Opera. Take a look at the result after installation of the style in Firefox.
Everything else is handled automatically from that moment on. If you are already on Google Search reload the page once so that the new script gets picked up.
Update: If you prefer to use a userscript instead, I suggest you take a look at Google Search Tools Back over at userscripts.org. The script keeps the main bar on top of the search results, but moves the Search Tools back to the left sidebar.
What's interesting in this regard is that it adds "more" options to the sidebar than the style. If you compare the screenshots you will notice that it adds an option to define a custom date range for the results and various search filters like listing sites with images, dictionary sites, related searches or translated foreign pages.
Update 2: The userscript linked above does not seem to be working anymore. I have found another script that you can make use of instead.
Update 3: The "other userscript" has been removed from the Userscripts website. Use Google Bar Classic Redone instead.
Update 4: The script is back again.
