Set the necessary parameters (one or more) for each main search category (BIOLOGICAL ORGANISM, SYSTEMS AND ORGANS, AGE OF THE OBJECT, DETECTION METHOD, ASPECTS) to filter only the works you need. You can expand categories into subcategories by clicking on the triangular bracket to the left of each item. If there is no such bracket, then such a subcategory is final and is not disclosed further. Clicking the box to the left marks the category or subcategory as "selected". When "selecting" an item that contains nested subcategories, all of them will also become "selected". It is necessary to "choose" at least one position for each main category.

The search is configured so that within each main category it is possible to select a work even based on a partial match. For example, if you want to get works about horses, and at the same time in the category BIOLOGICAL ORGANISMS you have marked all ungulates, you will get works about horses, but also about cows. At the same time, it is necessary to completely match the search parameters you have chosen between the main categories (BIOLOGICAL ORGANISM, SYSTEMS AND ORGANS, AGE, METHOD, ASPECTS). That is, if you want to get papers on the structural asymmetry of the legs of adult horses, you should select "horses", "adults", "forelimbs" + "hindlimbs", and "structural". If one of these parameters is not selected, you will not receive the required selection of works. On the other hand, third-party works where, for example, the legs of dogs or the legs of old horses were studied, will not be included in the sample.

Such settings allow both to choose works on a narrow topic and to make broad comparisons. For example, you can select the option "adrenal glands" in the SYSTEMS AND ORGANS category, and at the same time select absolutely all items in all other categories. Then you will receive all available data on adrenal asymmetry (in any animal of any age, both structural and functional).

The last category, ASPECTS, is the least specific and allows for a more creative search. If you do not see the need for it, mark all positions of this category as "selected" when searching.

The resulting samples of works can be "narrowed" by applying the last two categories. You can specify a date range (years of work publication) and search for words that should be found in the bibliographic data and the annotation. If the last two categories are not filled in, they do not interfere with the filtering of works.

After pressing SEARCH, you get to the results page, where the search parameters you selected are displayed on the left, and the results in the form of bibliographic data (citations) of scientific works are in the center. Each of these works can be expanded to see the annotation to the right. You can return to the search and adjust its parameters.

A limitation of such a search system is the mixing of parameters that characterize the asymmetry itself with parameters that relate to the circumstances accompanying this asymmetry (causes, consequences, or correlations). For example, for work with a worse effect of a right-sided than a left-sided stroke on urinary disorder, the categories "brain", "stroke" and "bladder" will be labeled. But for the researcher. who is looking for works on bladder asymmetry, this work will be unnecessary - the bladder appears in it as a non-lateralized factor (a consequence of brain asymmetry). Such mixing is most often found in the SYSTEMS AND ORGANS category. On the other hand, this feature of the cataloging of works allows us to trace various connections accompanying the phenomenon of asymmetry.

P.S. Regarding the BIOLOGICAL ORGANISM category. The author is aware that modern taxonomy looks different. But for convenience, the "advanced" Protostomia (insects) and Deuterostome (vertebrates) were separated from the more primitive representatives of both clades. The selection of individual species within this category (besides humans, including the zebrafish, the fruit fly, and the nematode C. elegans) is dictated by a large number of works on these organisms.
