By default, Entrez searches your text in "All fields", which looks for the text anywhere in the entry. So if you're getting irrelevant results, try limiting your text to a particular field.
Don't know what fields you can search for? Use the Advanced search.
1. Click on advanced beneath the search bar.
2. Click the drop down menu under Builder to see what fields are stored in gene records.
This is a comprehensive list of all fields you can search for. Fields will vary by database. Example shown here is for the Gene database.
You can Search GEO Profiles by...

Available fields are listed in the drop down menus on the resulting page, and you can see what values are in these fields by clicking to the right of the search box.
Below is an image of what GEO Profiles search results look like.
To limit to a specific gene, you can enter the gene symbol (blue box). You can choose the organism (red box).
The center column contains the records that meet your search criteria. Each record includes a title, including the gene name and description, its annotation, the unique identifiers associated with the record (orange box), links to external databases, and a graphic depicting the differences in expression level of this gene in the sample groups included in the experiment.
The right hand column is the discovery column, which contains links to external databases and your search strategy.
To view an individual record, click on the graph on the right side of the record. Clicking the title will bring up a new search results page with only that record.
Each individual record contains a labled graph that shows differences in expression between two condidtions. In the case below, they are comparing control cells with those expressing a particular microarray in humans. The red bars show the expression level, and the blue squares indicate the expression percentile among all other genes in the sample.
Additionally, the table at the bottom provides links to information about each individual sample, and numeric expression values.
